FindGLIB2
---------
Try to locate the GLib2 library.
If found, this will define the following variables:
``GLIB2_FOUND``
True if the GLib2 library is available
``GLIB2_INCLUDE_DIRS``
The GLib2 include directories
``GLIB2_LIBRARIES``
The GLib2 libraries for linking
``GLIB2_INCLUDE_DIR``
Deprecated, use ``GLIB2_INCLUDE_DIRS``
``GLIB2_LIBRARY``
Deprecated, use ``GLIB2_LIBRARIES``
If ``GLIB2_FOUND`` is TRUE, it will also define the following
imported target:
``GLIB2::GLIB2``
The GLIB2 library
``GLIB2::GTHREAD2``
The GThread2 library (since 6.7.0)
``GLIB2::GOBJECT``
The GObject library (since 6.7.0)
``GLIB2::GIO``
The GIO library (since 6.7.0)
Since 5.41.0.
