KWINDOWSYSTEM_WAYLAND=ON pulled in an escalating chain — PlasmaWaylandProtocols, xkbcommon, then the KWayland QML plugin links Qt6::GuiPrivate and uses Qt private Wayland APIs likely to need further Redox porting. The SDDM greeter is a fullscreen client that links the core KWindowSystem library, not this plugin, so set KWINDOWSYSTEM_WAYLAND=OFF to unblock the greeter build (matches the recipe/s original "Wayland disabled" intent) and drop the plugin-only deps. Re-enable + port Qt6::GuiPrivate usage when wiring the full Plasma desktop.
