The qtquick-config.h file was being generated empty by the cmake build, causing 'division by zero in #if' errors in downstream consumers (SDDM, KWin) because QT_CONFIG(quick_shadereffect) and QT_CONFIG(quick_draganddrop) were undefined. Two fixes: 1. Explicitly enable QT_FEATURE_quick_shadereffect and QT_FEATURE_quick_draganddrop in the cmake configuration. 2. Add a safety net that regenerates qtquick-config.h with the required feature definitions if cmake produces an empty file.
