A cross Qt carrying qtdeclarative makes find_package(Qt6) demand a host Qt, because QML needs host-side tools: qmlcachegen, qmlimportscanner and qmltyperegistrar. depends already builds one. native_qt installs it to native/qt-host, and qt.mk passes that path to the cross Qt's own configure. What nobody passed it to was wowlet. Qt6Config re-runs the host-path setup when our project calls find_package, finds nothing, and stops with "To use a cross-compiled Qt, please set the QT_HOST_PATH cache variable". The Windows cross build has failed that way on every tag since qtdeclarative landed in June, which is why 5.1.4 shipped macOS and Linux but no exe. Stating it in the toolchain rather than in the workflow fixes every cross target and anyone building locally through depends, and the built-cache key already hashes this file, so the stale mingw tree is rebuilt rather than restored without the host Qt.
