1 dnl @synopsis AC_PATH_GENERIC(LIBRARY [, MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
3 dnl Runs a LIBRARY-config script and defines LIBRARY_CFLAGS and LIBRARY_LIBS
5 dnl The script must support `--cflags' and `--libs' args.
6 dnl If MINIMUM-VERSION is specified, the script must also support the
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.)
14 dnl AC_PATH_GENERIC(Foo, 1.0.0)
16 dnl would run `foo-config --version' and check that it is at least 1.0.0
18 dnl If so, the following would then be defined:
20 dnl FOO_CFLAGS to `foo-config --cflags`
21 dnl FOO_LIBS to `foo-config --libs`
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)
