SLOT="$(ver_cut 1)" # 0/libmutter_api_version - ONLY gnome-shell (or anything using mutter-clutter-<api_version>.pc) should use the subslot

# gnome-settings-daemon is build checked, but used at runtime only for org.gnome.settings-daemon.peripherals.keyboard gschema
# xorg-server is needed at build and runtime with USE=wayland for Xwayland
# v3.32.2 has many excessive or unused *_req variables declared, thus currently the dep order ignores those and goes via dependency() call order
