Cmake error with installing via Pip

[michel3vb]

Hello,

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

Python 3.9 Windows 10

Any idea how to fix this error?

Looking at https://github.com/scikit-build/scikit-build-core/issues/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!
