Is this ready for review? Looks like the clang MSVC runner failed. There are conflicts too apparently.

[macumber]

No I didn't get this working yet, looks like I can't convert to draft PR because of the conflict

[jmarrec]

why?

[jmarrec]

ok, I haven't found a way to get that working either... When using ninja it's nearly impossible to pass a toolset without using a toolset file...

[jmarrec]

Hum, that makes me scared a bit.

[jmarrec]

Why not use ClangCL deps?

maybe need a UTILITIES_API on https://github.com/NREL/OpenStudio/blob/73c67b3969ab4963ecfacc735040d2b6dc99c931/src/utilities/core/Singleton.hpp#L40?

@macumber FYI I had to force push and it was refusing to merge properly (shorthand MERGE_HEAD not found or whatever)
