Some projects are definitely better off not supporting Windows. But it ought to be up to the developer to dictate that, not the build system. CMake manages to support Windows, Mac, Linux, and many other platforms, so I don't see why we should accept anything less out of a supposedly portable build system.

This is the same argument most people use for using Windows instead of Linux, especially in a corporate environment. I have to ask: don't your developers and users deserve something a little better than "barely good enough"? Are you really too old to learn something new?
