2022 build tools should work fine

If 2022 build tools works fine, then something has gone wrong with the check for build tools. From visual studio installer's side, everything looks as I would expect, but rustup-init still indicates that it can't find build tools.

At a minimum, I think you need to select these components when choosing individual components:

• MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest)
• Windows 10 SDK (10.0.20348.0)
• C++ CMake tools for Windows

(Assuming you are on x64 and not arm.)

Or, just choose the "Desktop development with C++", though that may include extra things you may not need. I'm not exactly sure why the cmake option is necessary.

Ah, C++ CMake tools was what I was missing. I didn't see that in the documentation. I'll see if there's a good spot to list those components in the documentation, but otherwise, you can consider this issue closed.

You shouldn't need CMake itself for a basic Rust install (though admittedly it can be useful for mixed code projects). I just tried a minimal setup of rust in a VM:

Ah, interesting. So, perhaps the real requirement is MSVC vLatest? I initially chose v142 because it mentioned VS2019.

Huh, that should work. But it doesn't. Rustup uses the cc crate to find out if MSVC is installed but that's failing to find it if the 2022 installer is used to install the 2019 build tools. Weird. I'll see if I can figure out why that is.

I had tested in a VM, and I encountered the same problem. Trying again, I see what I did wrong that required installing cmake.

I had selected MSVC v143 - VS 2022 C++ x64/x86 build tools (v14.32-17.2). The critical difference is the version at the end. Only when I choose the entry with the (Latest) version does it seem to work correctly. 🤷

See the issue linked above for the cause. A fix in cc-rs should not be too difficult.

Ran into this on a fresh install and can confirm the workaround is to use whatever the latest is for VS 2022.
