| # - 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.
