Problem description:

In Qt5, it was straightforward to work with QML resources in a static library. We simply created a .qrc file to include the QML files along with a qmldir, set QML_IMPORT_PATH for detection in Qt Creator, and used the Q_INIT_RESOURCE macro to initialize resources at runtime.

However, in Qt6, with the introduction of new patches and changes in the CMake workflow, we now need to use the qt_add_qml_module function to generate a .qrc file for QML files.

I also found the generated qrc file and CPP-initialize file. Both files not use the Q_INIT_RESOURCE macros. Which suggests that in a static build, the resources will not be loaded.

QT_DECLARE_EXTERN_RESOURCE(qmake_QEQuick3d)

namespace {
    struct resourceReferenceKeeper {
        resourceReferenceKeeper() { QT_KEEP_RESOURCE(qmake_QEQuick3d) }
    } resourceReferenceKeeperInstance;
}

Questions:

• What steps should we take when working with a static library that includes QML files?
• Specifically, where should we place the Q_INIT_RESOURCE macro in this new Qt6 setup?

If anyone has experience in packing qml in qt6 into a static library, please share.
