# Note: even if we have Gtk2 and Gtk3 support in Buildroot, we
# explicitly disable support for them, in order to avoid the following
# circular dependencies:
#
#  avahi -> libglade -> libgtk2 -> cups -> avahi
#  avahi -> libgtk3 -> cups -> avahi
#
# Since Gtk2 and Gtk3 in Avahi are only used for some example/demo
# programs, we decided to disable their support to solve the circular
# dependency.
