+Subject: [PATCH] Fix build with -xcb and -no-libinput
+
+Since a34e81ab [1], 'xkbcommon_support' is under
+'src/platformsupport/input', and will not be defined when building
+with -no-libinput, and as such, 'xkbcommon_support-private' added in
+'src/plugins/platforms/xcb/xcb_qpa_lib.pro' will be unknown.
