If cmake isn't going to be able to query the Makefiles and adjust to
changes we make there, changing our Windows build system from MSVC to
cmake takes us from maintaining 1.1 build systems to two build systems,
and I don't think anyone wants that.

If we go to cmake, I think we need to agree we will eventually _only_
use cmake. I don't think having two build systems we have to maintain
is better than 1.1 build systems where we can mostly ignore 0.1 of that.
