Cmake error with installing via Pip

Hello,

I got the following error after trying to install Ruckig with Pip:

Any idea how to fix this error?

Looking at scikit-build/scikit-build-core#900, it seems that pip is not able to find the MSVC toolchain for building Ruckig on your computer. Is MSVC or another compiler installed?

Installed MSVC and that fixed the problem. Thank you very much!
