# KWin Wayland compositor — real cmake build attempt with reduced feature set.
# DRM backend → scheme:drm, libinput → via evdevd, session → seatd.
# Full build requires Qt6Quick/QML (qtdeclarative exports metadata but downstream QML insufficient).
# Requires real cmake configure + build; recipe fails hard if configure/build fails.
