-are permitted in any medium without royalty provided the copyright
-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  5. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
-   The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
-   The first method involves providing an override variable for each
-affected directory.  For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'.  Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================

-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug.  Until the bug is fixed you can use this workaround:
-
-     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-==============================================================================
-the zexy external is a collection of externals for miller.s.puckette's 
-realtime-computermusic-environment called "puredata" (or abbreviated "pd")
-this zexy external will be of no use, if you don't have a running version of 
-pd on your system.
-check out for http://pd.iem.at to learn more about pd and how to get it 
-
-note: the zexy external is published under the Gnu General Public License 
-that is included (GnuGPL.txt). some parts of the code are taken directly 
-from the pd source-code, they, of course, fall under the license pd is 
-published under.
-
-
-
-installation::
-==============================================================================
-
-linux, irix, osx, mingw,... :
-------------------------------------------------------------------------------
-see INSTALL for more detailed instructions
-
-#0> ./autogen.sh
-#1> ./configure
-#2> make
-#3> make install
-
-installation directory:
-by defaultm zexy will install into /usr/local/lib/pd/extra/zexy
-the path can be changed via the "--prefix", or "--libdir"
-e.g. "./configure --prefix=/usr" -> /usr/lib/pd/extra/zexy
-e.g. "./configure --libdir=/tmp/foo" -> /tmp/foo/zexy
-
-puredata headers:
-zexy needs to find the Pd headers (and Pd.lib on some systems) during the build
-process.
-if you have installed the headers in a non-standard location, you can specify
-them with the "--with-pd" option:
-"./configure --with-pd=/usr/include/pd" will add /usr/include/pd to the INCLUDE
-path.
-"./configure --with-pd=/home/me/src/Pd-0.43.1" can be used to add
-/home/me/src/Pd-0.43.1/src to the INCLUDEs and /home/me/src/Pd-0.43.1/bin to the
-library search path
-
-custom external extension:
-zexy does it's best to determine the correct external extension for your system.
-e.g. it will use "dll" on w32, or "pd_linux" on linux.
-if - for whatever obscure reasons - you want to force the extension to certain
-value, you can use the "--with-extension" flag:
-"./configure --with-extension=l_ia64" will use "l_ia64" for the resulting
-binaries
-
-SSE2 (SIMD):
-by default zexy is compiled without SIMD optimization (recently there have been
-reports about crashes, when SSE2 was enabled; until this is fixed, the default
-is to use the safe fallback)
-if you want to enable SSE2 optimization, configure with
-"./configure --enable-simd=SSE2"
-
-multi-object vs single-object libraries:
-by default, zexy builds a single library "zexy" that contains all objects.
-if - for some obscure reason - you insist on having a lot of small libraries
-each containing a single object, you can enable this by using the
-"--disable-library" flag
-
-parallel port support:
-if you don't want the parallel-port object [lpt] you can disable it with
-	"--disable-lpt"
- (e.g.: because you don't have a parallel-port)
-
-
-fat (multiarch) binaries:
-for building multi-arch binaries (currently only supported on OSX), specify the
-wanted architectures in the "--enable-fat-binary" flag
-e.g. "./configure --enable-fat-binary=i386,ppc --with-extension=d_fat"
-
-win32 :
-------------------------------------------------------------------------------
-
-to compile: 
- + w/ MSVC use the build project found in build/win-vs*/
- OR
- + with GCC configure your pd path, eg:
-	#> ./configure --prefix=/c/program/pd; make; make install
- OR
- + cross-compilation for windows on linux using mingw (assumes that the 
-   crosscompiler is "i586-mingw32msvc-cc")
-	#> ./configure --host=i586-mingw32msvc --with-extension=dll \
-	   --disable-PIC --with-pd=/path/to/win/pd/
-	#> make CFLAGS="-fno-unit-at-a-time"
-     notes: configure tries to set the CFLAGS to "-g -O2" if the compiler
-            accepts this; however, this optimization sometimes generates 
-	    binaries that cannot be loaded by pd; it seems that disabling
-	    the "unit-at-a-time" optimization (which gets enabled by "-O2")
-	    is the cause of this problem. turning it off might help
-
-making pd run with the zexy external::
-==============================================================================
-make sure, that pd will be looking at this location 
-(add "-path <mypath>/pd/externs" either to your .pdrc or each time 
-you execute pd)
-make sure, that you somehow load the zexy external (either add "-lib zexy" 
-(if you advised pd somehow to look at the correct place) 
-or "-lib <myzexypath>/zexy" to your startup-script (.pdrc or whatever) 
-or load it via the object "zexy" at runtime

+"%AppData%\Pd\extra\" (Windows).
+if this is not an option, either add the path to your "Path..." settings in pd,
+or start pd with the cmdline option "-path /path/where/zexy/lives" (you can omit
+the trailing "/zexy" component of the path)
+
+make sure, that you somehow load the zexy external, either by adding "zexy" to
+the "Startup..." libraries (or by starting pd with "-lib zexy"), or (and this is
+the preferred method) by adding something like the following to your patches:
+
+    [declare -path zexy -lib zexy]
+

+
+
+installation::
+==============================================================================
+
+linux, irix, osx, mingw,... :
+------------------------------------------------------------------------------
+
+you will need to have Pd installed, and a C-compiler (preferably gcc)
+as well as a GNUmake compatible implementation of 'make'.
+
+on windows, you also need MSYS2/MinGW installed.

-build-instructions for zexy
-===========================
-
-
-autoconf/make
-=============
-this is the preferred way to build zexy, if your system supports autoconf/make. 
-such systems include:
-- linux / gcc
-- os-x / gcc
-- windows / mingw
-- windows / cygwin
-- freebsd
-- ...
-
-just go into the zexy/src/ directory, and run
- % make
-or alternatively:
- % aclocal
- % autoconf
- % ./configure
- % make
-
-use
- % ./configure --help
-to see flags you can pass to configure to get special builds
-
-
-
-
-Microsoft Visual Studio
-=======================
-use the provided project-files in the directories
-win-nmake: for nmake based builds
-win-vs6: for Microsoft VisualStudio 6
-win-vs2003: for Microsoft VisualStudio .NET 2003

+v0.6.0, dated 2019-12-21
+- detect target platform (OS and architecture) rather than build platform (#55)
+- introduce optional user variable 'PLATFORM' for cross compilation

+# Makefile.pdlibbuilder dated 2019-12-21
+version = 0.6.0
+
+# Helper makefile for Pure Data external libraries.
+# Written by Katja Vetter March-June 2015 for the public domain. No warranties.
+# Inspired by Hans Christoph Steiner's Makefile Template and Stephan Beal's
+# ShakeNMake.
+#
+# Grab the newest version of Makefile.pdlibbuilder from
+#    https://github.com/pure-data/pd-lib-builder/
+#
+# GNU make version >= 3.81 required.
+#
+#
+#=== characteristics ===========================================================
+#
+#
+# - defines build settings based on autodetected OS and architecture
+# - defines rules to build Pd class- or lib executables from C or C++ sources
+# - defines rules for libdir installation
+# - defines convenience targets for developer and user
+# - evaluates implicit dependencies for non-clean builds
+#
+#
+#=== basic usage ===============================================================
+#
+#
+# In your Makefile, define your Pd lib name and class files, and include
+# Makefile.pdlibbuilder at the end of the Makefile. Like so:
+#
+#    ________________________________________________________________________
+#
+#     # Makefile for mylib
+#
+#     lib.name = mylib
+#
+#     class.sources = myclass1.c myclass2.c
+#
+#     datafiles = myclass1-help.pd myclass2-help.pd README.txt LICENSE.txt
+#
+#     include Makefile.pdlibbuilder
+#    ________________________________________________________________________
+#
+#
+# For files in class.sources it is assumed that class basename == source file
+# basename. The default target builds all classes as individual executables
+# with Pd's default extension for the platform. For anything more than the
+# most basic usage, continue reading.
+#
+#
+#=== list of Makefile.pdlibbuilder API variables ===============================
+#
+#
+# Variables available for definition in your library Makefile:
+#
+# - lib.name
+# - lib.setup.sources
+# - class.sources
+# - common.sources
+# - shared.sources
+# - <classname>.class.sources
+# - <classname>.class.ldflags
+# - <classname>.class.ldlibs
+# - cflags
+# - ldflags
+# - ldlibs
+# - datafiles
+# - datadirs
+# - makefiles
+# - makefiledirs
+# - externalsdir
+#
+# Optional multiline defines evaluated per operating system:
+#
+# - forLinux
+# - forDarwin
+# - forWindows
+#
+# Variables available for your makefile or make command line:
+#
+# - make-lib-executable
+# - suppress-wunused
+#
+# Path variables for make command line or environment:
+#
+# - PDDIR
+# - PDINCLUDEDIR
+# - PDBINDIR
+# - PDLIBDIR
+#
+# Standard make variables for make command line or environment:
+#
+# - CPPFLAGS
+# - CFLAGS
+# - LDFLAGS
+# - CC
+# - CXX
+# - INSTALL
+# - STRIP
+# - DESTDIR
+#
+# Optional user variables for make command line or environment:
+#
+# - PLATFORM
+#
+# Deprecated path variables:
+#
+# - pdincludepath
+# - pdbinpath
+# - objectsdir
+#
+#
+#=== descriptions of Makefile.pdlibbuilder API variables =======================
+#
+#
+# lib.name:
+# Name of the library directory as it will be installed / distributed. Also the
+# name of the lib executable in the case where all classes are linked into
+# a single binary.
+#
+# lib.setup.sources:
+# Source file(s) (C or C++) which must be compiled only when linking all classes
+# into a single lib binary.
+#
+# class.sources:
+# All sources files (C or C++) for which the condition holds that
+# class name == source file basename.
+#
+# <classname>.class.sources:
+# Source file(s) (C or C++) specific to class <classname>. Use this for
+# multiple-source classes or when class name != source file basename.
+#
+# common.sources:
+# Source file(s) which must be statically linked to each class in the library.
+#
+# shared.sources:
+# Source file(s) (C or C++) to build a shared dynamic link lib, to be linked
+# with all class executables.
+#
+# cflags, ldflags, ldlibs:
+# Define cflags (preprocessor&compiler), ldflags (linker) and ldlibs (dynamic
+# link libs) for the whole library. These flags are added to platform-specific
+# flags defined by Makefile.pdlibbuilder.
+#
+# <classname>.class.ldflags and <classname>.class.ldlibs:
+# Define ldflags resp. ldlibs specific to class <classname>. These flags are
+# added to platform-specific flags defined by Makefile.pdlibbuilder, and flags
+# defined in your Makefile for the whole library. Note: cflags can not be
+# defined per class in the current implementation.
+#
+# datafiles and datadirs:
+# All extra files you want to include in binary distributions of the
+# library: abstractions and help patches, example patches, meta patch, readme
+# and license texts, manuals, sound files, etcetera. Use 'datafiles' for all
+# files that should go into your lib rootdir and 'datadirs' for complete
+# directories you want to copy from source to distribution.
+#
+# forLinux, forDarwin, forWindows:
+# Shorthand for 'variable definitions for Linux only' etc. Use like:
+#    define forLinux
+#      cflags += -DLINUX
+#      class.sources += linuxthing.c
+#    endef
+#
+# makefiles and makefiledirs:
+# Extra makefiles or directories with makefiles that should be made in sub-make
+# processes.
+#
+# make-lib-executable:
+# When this variable is defined 'yes' in your makefile or as command argument,
+# Makefile.pdlibbuilder will try to build all classes into a single library
+# executable (but it will force exit if lib.setup.sources is undefined).
+# If your makefile defines 'make-lib-executable=yes' as the library default,
+# this can still be overridden with 'make-lib-executable=no' as command argument
+# to build individual class executables (the Makefile.pdlibbuilder default.)
+#
+# suppress-wunused:
+# When this variable is defined ('yes' or any other value), -Wunused-variable,
+# -Wunused-parameter, -Wunused-value and -Wunused-function are suppressed,
+# but the other warnings from -Wall are retained.
+#
+# PDDIR:
+# Root directory of 'portable' pd package. When defined, PDINCLUDEDIR and
+# PDBINDIR will be evaluated as $(PDDIR)/src and $(PDDIR)/bin.
+#
+# PDINCLUDEDIR:
+# Directory where Pd API m_pd.h should be found, and other Pd header files.
+# Overrides the default search path.
+#
+# PDBINDIR:
+# Directory where pd.dll should be found for linking (Windows only). Overrides
+# the default search path.
+#
+# PDLIBDIR:
+# Root directory for installation of Pd library directories. Overrides the
+# default install location.
+#
+# DESTDIR:
+# Prepended path component for staged install.
+#
+# PLATFORM:
+# Target platform for cross compilation in the form of GNU triplet:
+# cpu-vendor-os. Example: x86_64-w64-mingw32. This specifies the tool chain that
+# pdlibbuilder will use, if installed and locatable. System and architecture
+# will then be autodefined accordingly. In most cases no other variables need to
+# be overridden.
+#
+# CPPFLAGS:
+# Preprocessor flags which are not strictly required for building.
+#
+# CFLAGS:
+# Compiler flags which are not strictly required for building. Compiler flags
+# defined by Makefile.pdlibbuilder for warning, optimization and architecture
+# specification are overriden by CFLAGS.
+#
+# LDFLAGS:
+# Linker flags which are not strictly required for building. Linker flags
+# defined by Makefile.pdlibbuilder for architecture specification are overriden
+# by LDFLAGS.
+#
+# CC and CXX:
+# C and C++ compiler programs as defined in your build environment.
+#
+# INSTALL
+# Definition of install program.
+#
+# STRIP
+# Name of strip program. Default 'strip' can be overridden in cross compilation
+# environments.
+#
+# objectsdir:
+# Root directory for installation of Pd library directories, like PDLIBDIR but
+# not overridable by environment. Supported for compatibility with pd-extended
+# central makefile, but deprecated otherwise.
+#
+# pdincludepath, pdbinpath:
+# As PDINCLUDEDIR and PDBINDIR but not overridable by environment. Deprecated
+# as user variables.
+#
+#
+#=== paths =====================================================================
+#
+#
+# Source files in directories other than current working directory must be
+# prefixed with their relative path. Do not rely on VPATH or vpath.
+# Object (.o) files are built in the directory of their source files.
+# Executables are built in current working directory.
+#
+# Default search path for m_pd.h and other API header files is platform
+# dependent, and overridable by PDINCLUDEDIR:
+#
+# Linux:    /usr/include/pd
+#
+# OSX:      /Applications/Pd*.app/Contents/Resources/src
+#
+# Windows:  %PROGRAMFILES%/Pd/src
+#           %PROGRAMFILES(X86)%/Pd/src (32 bit builds on 64 bit Windows)
+#
+# Default search path for binary pd.dll (Windows), overridable by PDBINDIR
+#
+#           %PROGRAMFILES%/Pd/bin
+#           %PROGRAMFILES(X86)%/Pd/bin (32 bit builds on 64 bit Windows)
+#
+# Default location to install pd libraries is platform dependent, and
+# overridable by PDLIBDIR:
+#
+# Linux:    /usr/local/lib/pd-externals
+# OSX:      ~/Library/Pd
+# Windows:  %APPDATA%/Pd
+#
+# https://puredata.info/docs/faq/how-do-i-install-externals-and-help-files
+# The rationale for not installing to ~/pd-externals by default on Linux
+# is that some people share the home dir between 32 and 64 bit installations.
+#
+#
+#=== targets ===================================================================
+#
+#
+# all: build $(executables) plus optional post target
+# post: target to build after $(executables)
+# alldebug: build all with -g option turned on for debug symbols
+# <classname>: force clean build of an individual class
+# <sourcefile>.pre: make preprocessor output file in current working directory
+# <sourcefile>.lst: make asm/source output file in current working directory
+#
+# install: install executables and data files
+# clean: remove build products from source tree
+#
+# help: print help text
+# vars: print makefile variables
+# allvars: print all variables
+# depend: print generated prerequisites
+# dumpmachine: print compiler output of option '-dumpmachine'
+# coffee: dummy target
+#
+# Variable $(executables) expands to class executables plus optional shared lib,
+# or alternatively to single lib executable when make-lib-executable=true.
+# Targets pre and post can be defined by library makefile. Make sure to include
+# Makefile.pdlibbuilder first so default target all will not be redefined.
+#
+#
+#=== Pd-extended libdir concept ================================================
+#
+#
+# For libdir layout as conceived by Hans-Christoph Steiner, see:
+#
+# https://puredata.info/docs/developer/Libdir
+#
+# Files README.txt, LICENSE.txt and <lib.name>-meta.pd are part of the libdir
+# convention. Help patches for each class and abstraction are supposed to be
+# available. Makefile.pdlibbuilder does not force the presence of these files
+# however. It does not automatically include such files in libdir installations.
+# Data files you want to include in distributions must be defined explicitly in
+# your Makefile.
+#
+#
+#=== Makefile.pdlibbuilder syntax conventions ==================================
+#
+#
+# Makefile.pdlibbuilder variable names are lower case. Default make variables,
+# environment variables, and standard user variables (CC, CXX, CFLAGS, DESTDIR)
+# are upper case. Use target 'allvars' to print all variables and their values.
+#
+# 'Fields' in data variables are separated by dots, like in 'foo.class.sources'.
+# Words in variables expressing a function or command are separated by dashes,
+# like in 'make-lib-executable'.
+#
+#
+#=== useful make options =======================================================
+#
+#
+# Use 'make -d <target>' to print debug details of the make process.
+# Use 'make -p <target>' to print make's database.
+#
+#
+#=== TODO ======================================================================
+#
+#
+# - decide whether to use -static-libgcc or shared dll in MinGW
+# - cygwin support
+# - android support
+# - figure out how to handle '$' in filenames
+# - add makefile template targets dpkg-source dist libdir distclean tags?
+#
+#

+
+### Makefile.pdlibbuilder ###
+
+Helper makefile for Pure Data external libraries. Written by Katja Vetter
+March-June 2015 for the public domain and since then developed as a Pd
+community project. No warranties. Inspired by Hans Christoph Steiner's Makefile
+Template and Stephan Beal's ShakeNMake.
+
+GNU make version >= 3.81 required.
+
+
+### characteristics ###
+
+
+* defines build settings based on autodetected target platform
+* defines rules to build Pd class- or lib executables from C or C++ sources
+* defines rules for libdir installation
+* defines convenience targets for developer and user
+* evaluates implicit dependencies for non-clean builds
+
+
+### basic usage ###
+
+
+In your Makefile, define your Pd lib name and class files, and include
+Makefile.pdlibbuilder at the end of the Makefile. Like so:
+
+
+      # Makefile for mylib
+
+      lib.name = mylib
+
+      class.sources = myclass1.c myclass2.c
+
+      datafiles = myclass1-help.pd myclass2-help.pd README.txt LICENSE.txt
+
+      include Makefile.pdlibbuilder
+
+
+For files in class.sources it is assumed that class name == source file
+basename. The default target builds all classes as individual executables
+with Pd's default extension for the platform. For anything more than the
+most basic usage, read the documentation sections in Makefile.pdlibbuilder.
+
+
+### paths ###
+
+
+Makefile.pdlibbuilder >= v0.4.0 supports pd path variables which can be
+defined not only as make command argument but also in the environment, to
+override platform-dependent defaults:
+
+PDDIR:
+Root directory of 'portable' pd package. When defined, PDINCLUDEDIR and
+PDBINDIR will be evaluated as $(PDDIR)/src and $(PDDIR)/bin.
+
+PDINCLUDEDIR:
+Directory where Pd API m_pd.h should be found, and other Pd header files.
+Overrides the default search path.
+
+PDBINDIR:
+Directory where pd.dll should be found for linking (Windows only). Overrides
+the default search path.
+
+PDLIBDIR:
+Root directory for installation of Pd library directories. Overrides the
+default install location.
+
+
+### documentation ###
+
+
+This README.md provides only basic information. A large comment section inside
+Makefile.pdlibbuilder lists and explains the available user variables, default
+paths, and targets. The internal documentation reflects the exact functionality
+of the particular version. For suggestions about project maintenance and
+advanced compilation see tips-tricks.md.
+
+
+### versioning ###
+
+
+The project is versioned in MAJOR.MINOR.BUGFIX format (see http://semver.org),
+and maintained at https://github.com/pure-data/pd-lib-builder. Pd lib developers
+are invited to regulary check for updates, and to contribute and discuss
+improvements here. If you really need to distribute a personalized version with
+your library, rename Makefile.pdlibbuilder to avoid confusion.
+
+
+### examples ###
+
+The list of projects using pd-lib-builder can be helpful if you are looking for
+examples, from the simplest use case to more complex implementations.
+
+- helloworld: traditional illustration of simplest use case
+- pd-windowing: straightforward real world use case of a small library
+- pd-nilwind / pd-cyclone: more elaborate source tree
+- zexy: migrated from autotools to pd-lib-builder

+pd-lib-builder cheatsheet
+=========================
+
+# Creating special builds
+
+## cross-compiling on linux x86_64 for other platforms
+
+Using pd-lib-builder >=0.6.0 we can define variable `PLATFORM` to specify a 
+target triplet for cross-compilation. Example to build W32 binaries (assuming 
+package `mingw-w64` is installed and a W32 package for Pd is unzipped into a 
+path `${PDWIN32}`:
+
+    make PLATFORM=x86_64-w64-mingw32 PDDIR="${PDWIN32}"
+
+#### older pd-lib-builder versions
+
+Using pd-lib-builder < 0.6.0, in the absence of variable `PLATFORM`, you would
+instead override variables `system`, `target.arch`, `CC` and / or `CXX`,
+`STRIP`. Example:
+
+    make system=Windows target.arch=i686 CC=i686-w64-mingw32-gcc STRIP=i686-w64-mingw32-strip PDDIR="${PDWIN32}"
+
+#### toolchains
+
+Cross toolchains for relevant platforms in Debian Buster (install g++ 
+with dependencies for a given platform to get the whole tool chain):
+
+- `arm-linux-gnueabihf`
+- `aarch64-linux-gnu`
+- `i686-linux-gnu`
+- `i686-w64-mingw32` and `x86_64-w64-mingw32` (install `mingw-w64`)
+
+OSX/MacOS cross tool chains are not distributed by Debian. Use project 
+`osxcross` from Thomas Poechtraeger to create the tools.
+
+## building double-precision externals
+
+At the time of writing (2018-02) there is no official Pd that supports
+double-precision numbers yet.
+However, if you do get hold of an experimental double-precision Pd, you can
+easily build your externals for 64-bit numbers:
+
+   make CPPFLAGS="-DPD_FLOATSIZE=64"
+
+## building externals for W64 (64-bit Windows)
+
+At the time of writing (2018-02) there is no official Pd that supports
+W64 yet.
+However, if you do get hold of an experimental W64 Pd, you can
+easily build your externals for this environment with
+
+   make CPPFLAGS="-DPD_LONGINTTYPE=__int64" CC=x86_64-w64-mingw32-gcc
+
+
+To build a double-precision external for W64, use something like:
+
+   make CPPFLAGS="-DPD_LONGINTTYPE=__int64 -DPD_FLOATSIZE=64" CC=x86_64-w64-mingw32-gcc
+
+
+## TODO universal binaries on OSX
+
+
+# Project management
+
+In general it is advised to put the `Makefile.pdlibbuilder` into a separate
+subdirectory (e.g. `pd-lib-builder/`).
+This makes it much easier to update the `Makefile.pdlibbuilder` later
+
+You *should* also use a variable to the actual path of the Makefile.pdlibbuilder
+(even if you keep it in the root-directory), as this allows easy experimenting
+with newer (or older) (or site-specific) versions of the pd-lib-builder
+Makefile.
+
+~~~make
+PDLIBBUILDER_DIR=pd-lib-builder/
+include $(PDLIBBUILDER_DIR)/Makefile.pdlibbuilder
+~~~
+
+## Keeping pd-lib-builder up-to-date
+
+### `git subtree`
+
+With git-subtrees, you make the pd-lib-builder repository (or any other
+repository for that matter) part of your own repository - with full history and
+everything - put nicely into a distinct subdirectory.
+
+Support for *manipulating* subtrees has been added with Git-v1.7.11 (May 2012).
+The nice thing however is, that from "outside" the subtree is part of your
+repository like any other directory. E.g. older versions of Git can clone your
+repository with the full subtree (and all it's history) just fine.
+You can also use git-archive to make a complete snapshot of your repository
+(including the subtree) - nice, if you e.g. want self-contained downloads of
+your project from git hosting platforms (like Github, Gitlab, Bitbucket,...)
+
+In short, `git subtree` is the better `git submodule`.
+
+So here's how to do it:
+
+#### Initial setup/check-out
+This will create a `pd-lib-builder/` directory containing the full history of
+the pd-lib-builder repository up to its release `v0.5.0`
+
+~~~sh
+git subtree add --prefix=pd-lib-builder/ https://github.com/pure-data/pd-lib-builder v0.5.0
+~~~
+
+This will automatically merge the `pd-lib-builder/` history into your current
+branch, so everything is ready to go.
+
+#### Cloning your repository with the subtree
+Nothing special, really.
+Just clone your repository as always:
+
+~~~sh
+git clone https://git.example.org/pd/superbonk~.git
+~~~
+
+#### Updating the subtree
+Time passes and sooner or later you will find, that there is a shiny new
+pd-lib-builder with plenty of bugfixes and new features.
+To update your local copy to pd-lib-builder's current `master`, simply run:
+
+~~~sh
+git subtree pull --prefix pd-lib-builder/ https://github.com/pure-data/pd-lib-builder master
+~~~
+
+#### Pulling the updated subtree into existing clones
+Again, nothing special.
+Just pull as always:
+
+~~~sh
+git pull
+~~~
+
+
+#### Further reading
+More on the power of `git subtree` can be found online
+- https://medium.com/@v/git-subtrees-a-tutorial-6ff568381844
+- https://www.atlassian.com/blog/git/alternatives-to-git-submodule-git-subtree
+- ...
+
+### ~~`git submodule`~~ [DISCOURAGED]
+
+
+#### Initial setup/check-out
+To add a new submodule to your repository, just run `git submodule add` and
+commit the changes:
+
+~~~sh
+git submodule add https://github.com/pure-data/pd-lib-builder
+git commit .gitmodules pd-lib-builder/ -m "Added pd-lib-builder as git-submodule"
+~~~
+
+#### Cloning your repository with the submodule
+
+When doing a fresh clone of your repository, pass the `--recursive` option to
+automatically fetch all submodules:
+
+~~~sh
+git clone --recursive https://git.example.org/pd/superbonk~.git
+~~~
+
+If you've cloned non-recursively, you can initialize and update the submodules
+manually:
+
+~~~sh
+git submodule init
+git submodule update
+~~~
+
+#### Updating the submodule
+Submodules are usually fixed to a given commit in their repository.
+To update the `pd-lib-builder` submodule to the current `master` do something
+like:
+
+~~~sh
+cd pd-lib-builder
+git checkout master
+git pull
+cd ..
+git status pd-lib-builder
+git commit pd-lib-builder -m "Updated pd-lib-builder to current master"
+~~~
+
+#### Pulling the updated submodule into existing clones
+After you have pushed the submodule updates in your repository, other clones of
+the repository can be updated as follows:
+
+~~~sh
+git pull
+~~~
+
+The above will make your repository aware, that the submodule is out-of-sync.
+
+~~~sh
+$ LANG=C git status pd-lib-builder
+On branch master
+Your branch is up to date with 'origin/master'.
+
+Changes not staged for commit:
+  (use "git add <file>..." to update what will be committed)
+  (use "git checkout -- <file>..." to discard changes in working directory)
+
+	modified:   pd-lib-builder (new commits)
+$
+~~~
+
+In order to sync the submodule to the correct commit, run the following:
+
+~~~sh
+git submodule update
+~~~
+
+#### Drawbacks
+`git submodule` has a number of drawbacks:
+- it requires special commands to synchronize the submodules, in addition to
+  synching your repository.
+- you must make sure to use an URL for the submodule that is accessible to your
+  potential users. e.g. using `git@github.com:pure-data/pd-lib-builder` is bad,
+  because it requires everybody who wants to checkout your sources to have a
+  github-account - even if they could checkout *your* repository anonymously.
+- submodules will be excluded from `git archive`. This means, that if you use a
+  mainstream git provider (like Github, GitLab, Bitbucket,...) and make releases
+  by creating a `git tag`, the automatically generated zipfiles with the sources
+  will lack the submodule - and your users will not be able to compile your
+  source code.
+
+In general, I would suggest to **avoid** `git submodule`, and instead use the
+better `git subtree` (above).
