| # - 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. |
