Testing multiple build systems gets messy fast:

Would be nice to hide these files away someplace (if possible)

Oh, and add cmake --build . --config Release to .github/workflows/build.yml
Debug builds aren't that useful to non-developers, since they can't run them

I wouldn't wish having to install 50GBs of Visual Studio on my worst enemy

Finally, when I was going through the CMake tutorial I stopped just before adding a --version argument
Including the commit, build date & build system would be nice too

Summary

• cleaner top directory after building
• both Release & Debug builds in MSVC automated builds
• --version flag
