    XORG_WITH_GLIB: check for the GLib package
    
    XORG_WITH_GLIB([MIN-VERSION], [DEFAULT])
     ----------------------------------------
     Minimum version: 1.13.0
    
     GLib is a library which provides advanced data structures and functions.
     This macro enables a module to test for the presence of Glib.
    
     When used in conjunction with XORG_ENABLE_UNIT_TESTS, use both AM_CONDITIONAL
     ENABLE_UNIT_TESTS and HAVE_GLIB.
     Glib may be used for purpose other than testing
    
     Package builders should use --without-glib to ensure it does not get pulled in.
     Unit tests may or may not use GLib.
    
     Developers should use --with-glib to error out if GLib is missing.
    
     Interface to module:
     HAVE_GLIB: used in makefiles to conditionally build targets
     with_glib: used in configure.ac to know if GLib has been found
     --with-glib:	'yes' user instructs the module to use glib
    		'no' user instructs the module not to use glib
