# - Try to find dbusmenu-qt
# This module helps finding an installation of the DBusMenuQt library (see https://launchpad.net/libdbusmenu-qt/)
# Once done this will define
#
# DBUSMENUQT_FOUND - system has dbusmenu-qt
# DBUSMENUQT_INCLUDE_DIR - the dbusmenu-qt include directory
# DBUSMENUQT_LIBRARIES - the libraries needed to use dbusmenu-qt
# DBUSMENUQT_DEFINITIONS - Compiler switches required for using dbusmenu-qt
#
# The minimum required version of DBusMenuQt can be specified using the
# standard syntax, e.g. find_package(DBusMenuQt 0.6)
#
# WARNING: versions below 0.4.0 cannot be checked for.
# So if you want to have a version check, require at least 0.4.0 of dbusmenuqt.
