cc @ChrisDenton I would need some help on how to find clang-cl, here I just pass clang-cl.exe to windows_registry::find_tool if user prefers clang-cl over msvc, hoping it would find it, not sure if it is correct.

That might find it if it's installed with Visual Studio but it could be installed separately. We should more strongly prefer the environment for clang-cl (e.g. checking PATH as well).

Should add I a dedicated PATH checking logic for clang-cl.exe?
Or should I add that to windows_registry::find_tool?

I think adding dedicated PATH checking logic is the safest option.
It'd be nice if find_tool where consistent but it's possible people may use it to specifically find the VS installed version. So unless someone complains about the find_tool behaviour, I'm not sure if it's worth the (admittedly small) risk of breakage.
