   2 dnl
   3 dnl Runs a LIBRARY-config script and defines LIBRARY_CFLAGS and LIBRARY_LIBS
   4 dnl
   5 dnl The script must support `--cflags' and `--libs' args.
   6 dnl If MINIMUM-VERSION is specified, the script must also support the
   7 dnl `--version' arg.
   8 dnl If the `--with-library-[exec-]prefix' arguments to ./configure are given,
   9 dnl it must also support `--prefix' and `--exec-prefix'.
  10 dnl (In other words, it must be like gtk-config.)
  11 dnl
  12 dnl For example:
  13 dnl
  14 dnl    AC_PATH_GENERIC_MODIFIED(Foo, 1.0.0)
  15 dnl
  16 dnl would run `foo-config --version' and check that it is at least 1.0.0
  17 dnl
  18 dnl If so, the following would then be defined:
  19 dnl
  20 dnl    FOO_CFLAGS to `foo-config --cflags`
  21 dnl    FOO_LIBS   to `foo-config --libs`
  22 dnl
  23 dnl At present there is no support for additional "MODULES" (see AM_PATH_GTK)
  24 dnl (shamelessly stolen from gtk.m4 and then hacked around a fair amount)
