[Windows] Error in cmake

[erelsgl]

When I run cmake, I get the following error, which is apparently related to the version of visual studio and MS build tools. I installed several versions of these tools (2015, 2017, and the latest one - 2022), but the problem persists. What tools exactly do I need to build qdldl?

I have Windows 10 and Python 3.10.2 (latest version).

I think this error is related to the setup of the Visual Studio environment or the environment variables, because QDLDL should be able to be compiled with any MSVC toolchain. Maybe this thread on the Microsoft dev forums can help? https://developercommunity.visualstudio.com/t/build-tools-v143-not-found/1581981#T-N1585602

Any chance having a pre built wheel for Python 3.12 on Windows?
