Both approaches fail — redox-toolchain.cmake overrides include paths. Root cause: Qt6 cmake configs from qtdeclarative (built with qml_jit=OFF) do not export Qt6Qml/Qt6Quick include directories properly for downstream consumers. Headers exist at /usr/include/QtQml/QQmlEngine but cmake does not add -I paths. This is the precise QML gate mechanism.
