 #TODO: KWin Wayland compositor — DRM backend → scheme:drm, libinput → via evdevd, session → seatd
 # Stub deps remaining: libepoxy-stub, libudev-stub, lcms2-stub, libdisplay-info-stub
 # provide INTERFACE IMPORTED cmake targets so KWin links without real implementations.
+# Re-enabled (deps built): decorations, global shortcuts, runners, notifications, D-Bus
+# Still disabled: KCMS (QML), screen locking, tabbox, effects, X11, QML, signing docs
