This is a duplicate of #880. We plan to release a patch very soon.

I was wrong. This is actually a problem with VS 2019. I have a fix.

You should be able to work around the issue by setting the cmake.generator setting to "Visual Studio 16 2019".

After the fix is released, you'll need to rescan kits.

1.2.2 was released today. Please give that a try and let us know if you continue to have issues. You'll want to rescan for kits.
