# 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
#
# Since 5.41.0.
