[SOLVED] pip install python-qpid-proton: how to fix errors on windows?

While running pip install python-qpid-proton I got the following errors:

error: Microsoft Visual C++ 14.0 or greater is required.
I fixed this by installing Visual Studio Build Tools 2022 and Visual Studio Professional 2022
fatal error C1083: Cannot open compiler generated file
This error appears apparently if the path is too long. Therefore I changed the path of the Temp folder to a shorter path. I have done this by creating a new folder under C:\Windows\TEMP and changed setting the following environmental variables:
TEMP=C:\TEMP and TMP=C:\TEMP
After these two steps I get a different error. Has someone an idea how to solve this? Maybe there is also a different way to install python-qpid-proton on windows? I would appreciate that a lot...

The error comes after a lot of warnings in this form

Then there are the errors:
