This all adds up to a very confusing versioning. Would it be clearer to start using the Visual Studio versioning

and call the build methods along the lines of VS2015, VS2017 to keep track of what compiler product to install to get specific build system? Or

would it be better to go along with the version number of the compiler (e.g. 19.10), which is defined with _MSC_VER as e.g. 1910? Anyway, the MSC15 is not correct and I do not feel 14.10 is a strong identifier for the compiler either.
