    Description

      Building a simple project using static child modules fails to properly embed the QML resources. 
      This problem only happens with CMake 3.16, Qt <6.5, MinGW/GCC.
      It's fixed with CMake 3.19, Qt 6.7.2 or when using MSVC.

      I've made this MVP for Windows 6.5.3, to reproduce a bug that is occurring in 6.5.8 (Ubuntu and Yocto).

      Expected:

      • QML module importable
      • QML resources available at qrc:/qt/qml/Module/.....

      Current:

      • "QQmlApplicationEngine failed to load component
        qrc:/qt/qml/App/Main.qml:12:3: MyChild is not a type"
      • QML resource does not exist

       

      I've attached an MVP.

      The file path is clickable, so you can confirm that qrc:/qt/qml/Child/..... does not exist.
