Issues statically linking extension plugin on Windows Qt6

Related Stackoverflow question

I haven't been able to successfully link a static, prebuilt Extension Plugin. All examples require `qt_add_qml_module()`, which seems to require access to the source code.

The closest I have gotten is access to the C++ classes within the plugin, but no access to the QML classes.

When linking the external plugin in CMake the following error is generated:

TestPplugin.lib(TestPplugin_TestPPlugin.cpp.obj):-1: error: LNK2019: unresolved external symbol "void __cdecl qml_register_types_TestP(void)" (?qml_register_types_TestP@@YAXXZ) referenced in function "private: static __cdecl <lambda_aae1ac3daa5dcd67ebc864db46295620>::<lambda_invoker_cdecl>(class QtPrivate::QMetaTypeInterface const *,void *)" (?<lambda_invoker_cdecl>@<lambda_aae1ac3daa5dcd67ebc864db46295620>@@CA@PEBVQMetaTypeInterface@QtPrivate@@PEAX@Z)

 where TestP is the name of the plugin class.

Linking TestP.lib before TestPplugin (an action that isn't shown in any examples), we can access the C++ classes within the plugin, but the QML classes return "{ItemName} is unavailable. qrc:/TestP/{ItemName}.qml: No such file or directory}

If I'm doing something wrong, it would be appreciated if someone could create an example where you:

• Creates a new Quick App project in QtCreator
• Creates a new Quick2ExtensionPlugin in QtCreator
• Uses the Plugin in the App
