A relic from older times was the dependency of lxmenu-data for parts of the menus used in the “Applications menu” of the panel, in the LXQt Configuration Center and in PCManFm-Qt. This dependency is now replaced by lxqt-menu-data, concentrating all menu related files in one place, removing also a duplicate for LXQt Settings.

This are only changes “under the hood” so far but it allowed already to unify “Education” and “Science and Math” categories in one default “Education & Science” category.

To make sure that those files are always installed lxqt-panel, lxqt-config and libfm-qt require it now at build time.
