As a side thought, we could also move away from nmake when it comes to find out the version of Visual Studio used if Microsoft is lazy with nmake's version number. For example we could consider using "MSBuild.exe -version" and parse its output. This reports 16.1.XX.YY for me with VS 2019, and 14.0.XX.YY with VS 2015.
Not sure how portable that it though past those versions. Still, on HEAD and v12, we only support VS 2013 and newer versions, so we could integrate with it easily.
I agree that we can think of using MSBuild.exe instead of nmake. I am also
not sure whether MSBuild is available in all the visual studio versions [1].
