The Qt Design Studio does not generate the correct CMake files

The proper `CMake` files should be generated in Qt design studio if a user creates a new project and specifies a qt version in my case `5.15`, but I can see that the generated CMake files in my case are for `Qt6`, and so it cannot be compiled in `Qt5` since the CMake modules do not exist in this major version.

My target is `Qt5` as you can see in the picture below.
