# FindGObject
# ---------
#
# Try to locate the gobject-2.0 library.
# If found, this will define the following variables:
#
# ``GObject_FOUND``
#     True if the gobject-2.0 library is available
#
# If ``GObject_FOUND`` is TRUE, it will also define the following
# imported target:
#
# ``GObject::GObject``
#     The gobject-2.0 library
