Pretty much this, tried building with different Python versions, different CMake versions, keep running into the error when I run "cmake .. -G "Visual Studio 16 2019" -A x64" resulting in this:

Also I tried building v0.84.0 which is two versions old to make sure it wasn't just this release. I'm running a fresh "reset" (not the same as a clean install) of Windows 10 Pro.
