Unable to build dotnet/runtime due to cmake error about MultiThreadedDebug

[stephentoub]

I'm unable to build dotnet/runtime after sync'ing and trying to do a clean build:

  CMake Error in D:/repos/runtime/src/libraries/Native/Unix/System.Globalization.Native/CMakeLists.txt:
    MSVC_RUNTIME_LIBRARY value 'MultiThreadedDebug' not known for this ASM_MASM
    compiler.

Note I'm building on Windows; I don't know why it's trying to process a unix cmakelists.

@jkoritzinsky, I assume this is due to #41897?

Do I need to somehow update my local configuration?

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Try cleaning your artifacts folder. In the meantime, I’ll investigate to see if I can repro locally.

[stephentoub]

I've done a full git clean -xdf. No artifacts folder.

[jkoritzinsky]

I'm looking now.

[jkoritzinsky]

Which command are you using to build? (To make sure I'm checking the right execution sequence in CMake)

[jkoritzinsky]

This looks like it was a bug in CMake that was fixed in 3.16.4. I'll put out a PR with the fix ASAP (since our minimum on Windows is 3.15.5 and our recommended version is 3.16.0+).

[jkoritzinsky]

I have a fix in #44155. Can you pull down my PR and try building locally?

[stephentoub]

Trying...

[stephentoub]

Build is still going, but it's gotten past where it was failing before, so that's a good sign.

[jkoritzinsky]

Once your build passes, I'm comfortable merging in #44155 before CI finishes to unblock people.

[stephentoub]

It finished successfully. Thanks.
