    just find XCB as an optional dependency. You are not using XLib, so why bind it to whether XLib is found?

    why this variable?



startkde/kcminit/main.cpp

    as you are still using an QGuiApplication I suggest to introduce a test for the platform name. The reason: on e.g. Wayland you don't want to check the xcb connection - which would succeed in the case of XWayland.
