[Interest] Qt6 CMake Windows VS Debug Build Issues

[Alexandru Croitor]

Hi,

Thanks for the feedback.

I would appreciate if you could file 2 bug reports for the issues you encountered with the "Build System: CMake component".

I am not surprised about the long path issues, but the the clang one is strange.
Please provide your CMake configuration line and which clang libraries you used, in the bug reports.
