dnl @synopsis AC_CONFIG_LIBCONFIG_IN [(LIBRARY [, DESTINATION [, MODULES]])]
dnl
dnl Creates a custom LIBRARY-config script.  The script supports
dnl --cflags, --libs and --version options, as well as all of the
dnl standard configure variables e.g. --libdir and --sysconfdir.
dnl --prefix and --exec-prefix may be specified to override the
dnl defaults.  --help gives a complete list of available options.
dnl Modules allow multiple sets of --libs, --cflags and --version
dnl options to be used, and combined together.
dnl
dnl This macro saves you all the typing for a library-config.in script;
dnl you don't even need to distribute one along. Place this macro
dnl in your configure.ac, et voila, you got one that you want to install.
dnl
dnl The options:
dnl
dnl  $1 = LIBRARY       e.g. gtk, ncurses
dnl  $2 = DESTINATION   Directory path, e.g. src/scripts
dnl  $3 = MODULES       Additional library modules, not including the
dnl                     default ($1).
dnl
dnl It is suggested that the following CFLAGS and LIBS variables are
dnl used in your configure.in.  library_libs is *essential*.
dnl library_cflags is important, but not always needed.  If they do not
dnl exist, defaults will be taken from LIBRARY_CFLAGS, LIBRARY_LIBS
dnl (should be -llibrary *only*) and LIBRARY_LIBDEPS (-l options for
dnl libraries your library depends upon.
dnl LIBLIBRARY_LIBS is simply $LIBRARY_LIBS $LIBRARY_LIBDEPS.
dnl NB. LIBRARY and library are the name of your library, in upper and
dnl lower case repectively e.g. GTK, gtk.
dnl
dnl  LIBRARY_CFLAGS:    cflags for compiling libraries and example progs
dnl  LIBRARY_LIBS:      libraries for linking programs
dnl  LIBRARY_LIBDEPS*:  libraries for linking libraries against (needed
dnl                     to link -static
dnl  library_cflags*:   cflags to store in library-config
dnl  library_libs*:     libs to store in library-config
dnl  LIBLIBRARY_LIBS:   libs to link programs IN THIS PACKAGE ONLY against
dnl  LIBRARY_VERSION*:  the version of your library (x.y.z recommended)
dnl    *=required if you want sensible output, otherwise they will be
dnl      *guessed* (DWIM)
dnl
dnl Support for pkg-config is available by default.  libs, cflags and
dnl version information will be obtained from the pkg-config metadata
dnl file library.pc if it exists in the pkgconfig data directory.
dnl The above information still needs to be specified, as it will still
dnl be used if pkg-config is not found on the host system at configure
dnl time.
dnl
dnl -I and -L flags will be obtained from *both* pkgconfig and the script.
dnl AC_CONFIG_LIBCONFIG_IN_PKGCONFIG enables pkg-config support (default)
dnl AC_CONFIG_LIBCONFIG_IN_STATIC disables pkg-config support
dnl
dnl There is also an AC_SUBST(LIBRARY_CONFIG) that will be set to
dnl the name of the file that we output in this macro. Use as:
dnl
dnl  install-exec-local: install-config
dnl  install-config:
dnl     $(mkinstalldirs) $(DESTDIR)$(bindir)
dnl     $(INSTALL_EXEC) @LIBRARY_CONFIG@ $(DESTDIR)$(bindir)
dnl
dnl Or, if using automake:
dnl
dnl  bin_SCRIPTS = @LIBRARY_CONFIG@
dnl
dnl Based upon AC_CREATE_GENERIC_CONFIG (ac_create_generic_config.m4)
dnl by Guido Draheim <guidod@gmx.de> and gtk-config by Owen Taylor.
