| 1 | +# - Try to find Glib and its components (gio, gobject etc) |
| 2 | +# Once done, this will define |
| 3 | +# |
| 4 | +# GLIB_FOUND - system has Glib |
| 5 | +# GLIB_INCLUDE_DIRS - the Glib include directories |
| 6 | +# GLIB_LIBRARIES - link these to use Glib |
| 7 | +# |
| 8 | +# Optionally, the COMPONENTS keyword can be passed to find_package() |
| 9 | +# and Glib components can be looked for. Currently, the following |
| 10 | +# components can be used, and they define the following variables if |
| 11 | +# found: |
| 12 | +# |
| 13 | +# gio: GLIB_GIO_LIBRARIES |
| 14 | +# gobject: GLIB_GOBJECT_LIBRARIES |
| 15 | +# gmodule: GLIB_GMODULE_LIBRARIES |
| 16 | +# gthread: GLIB_GTHREAD_LIBRARIES |
| 17 | +# |
| 18 | +# Note that the respective _INCLUDE_DIR variables are not set, since |
| 19 | +# all headers are in the same directory as GLIB_INCLUDE_DIRS. |
