- # $Id$
- #
- # - Try to find Glib and its components (gio, gobject etc)
- # Once done, this will define
- #
- # GLIB_FOUND - system has Glib
- # GLIB_INCLUDE_DIRS - the Glib include directories
- # GLIB_LIBRARIES - link these to use Glib
- #
- # Optionally, the COMPONENTS keyword can be passed to find_package()
- # and Glib components can be looked for. Currently, the following
- # components can be used, and they define the following variables if
- # found:
- #
- # gio: GLIB_GIO_LIBRARIES
- # gobject: GLIB_GOBJECT_LIBRARIES
- # gmodule: GLIB_GMODULE_LIBRARIES
- # gthread: GLIB_GTHREAD_LIBRARIES
- #
- # Note that the respective _INCLUDE_DIR variables are not set, since
- # all headers are in the same directory as GLIB_INCLUDE_DIRS.
