See No CUDA toolset found log after -- CUDA Toolkit found. log

I have installed CUDA in version 12.5, which is detected by CMake and is visible in the terminal. The CUDA_PATH is also correctly set.
During trying to install, I see those logs:

  note: This error originates from a subprocess, and is likely not a problem with pip.

Did you forget to copy the four files from CUDA MSBuildExtensions directory to VS BuildCustomizations directory after installation? everything should be useful to locate them.
