#TODO: Qt6 shader tools — provides libQt6ShaderTools and the qsb host tool used by
# Qt Quick for runtime shader compilation. Host-side Qt6ShaderToolsTools metadata and qsb
# must be propagated into the shared QT_HOST_PATH for downstream modules to configure cleanly.
# Depends on qtbase being built first.
