dnl @synopsis AC_PATH_GENERIC(LIBRARY [, MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
dnl
dnl Runs a LIBRARY-config script and defines LIBRARY_CFLAGS and LIBRARY_LIBS
dnl
dnl The script must support `--cflags' and `--libs' args.
dnl If MINIMUM-VERSION is specified, the script must also support the
dnl `--version' arg.
dnl If the `--with-library-[exec-]prefix' arguments to ./configure are given,
dnl it must also support `--prefix' and `--exec-prefix'.
dnl (In other words, it must be like gtk-config.)
dnl
dnl For example:
dnl
dnl    AC_PATH_GENERIC(Foo, 1.0.0)
dnl
dnl would run `foo-config --version' and check that it is at least 1.0.0
dnl
dnl If so, the following would then be defined:
dnl
dnl    FOO_CFLAGS to `foo-config --cflags`
dnl    FOO_LIBS   to `foo-config --libs`
dnl
dnl At present there is no support for additional "MODULES" (see AM_PATH_GTK)
dnl (shamelessly stolen from gtk.m4 and then hacked around a fair amount)
