Compiling with MSVC

[sigmasoldi3r]

While it has been reported that the project can be compiled using MSVC compiler family, I can't get it to work.

There might be some version requirements, or a step that I'm missing. After tinkering for days, I can't get it to work.

What I'm using

• Visual Studio 2022
  • This includes Windows 11 SDK and Desktop
• Rust nightly
• LLVM installed via chocolatey

But when compiling the sys crate, it starts spamming errors such as:

...

(Which is weird, and probably something about compiler versions? clang flags maybe?)

Other paths

Also I've tried switching to the gnu compiler family, but always results in Cmake complaining about the generator type.

Any thoughts? Something I could try?
