Steps to reproduce

1. In Qt Design Studio, create a new project (Presets > General > Empty) that targets Qt 6.4. Don't edit it.
2. In Qt Creator, load the auto-generated top-level CMakeLists.txt file using a Qt 6.4.2 kit. Try to build and run the project.
3. Close Qt Creator and delete your build folder.
4. In Qt Design Studio, click "File" > "Export Project" > "Generate CMake build files..." > "OK"
5. In Qt Creator, re-load the top-level CMakeLists.txt. Try to build and run the project.

Outcomes

• At Step #2, the project runs fine
• At Step #5, the project no longer runs

Notes

• At Step #1, App.qml and Screen01.ui.qml are part of the CMake files
• Step #4 actually removes App.qml and Screen01.ui.qml, among other things
