When exporting an example project which uses Quick3D:

https://git.qt.io/public-demos/qtdesign-studio/-/tree/effectComposerExample

The Cmake exporter does not take the Quick3D models and meshes into the flow.

The project was done with Qt DS 4.5 originally.

Steps to reproduce

1. Enable Cmake creation from menu
2. Save the project in Qt DS
3. Open the project in Qt Creator with Qt 6.8 kit
4. Run Make

Expected result:

• CMake would prompt if 
  • Qt Quick Timeline
  • Qt Quick3D
  • Qt Shader tools

are missing.

Actual result:

• CMake stops only at Qt Shader tools. Missing Quick Timeline and Quick3D are discovered only when user tries to run the Creator project.
