The concern with multiple build systems is more to do with the chilling 
effect.

We all know that feeling when you *should* go and fix it, only that you 
don't have a Makefile build around, or you're on Windows / BSD or some 
place, so you just end up lumping things into an existing module that 
happens to already exist in both.

A better motivator would be to cite the remaining issues with CMake.

I always feel that we're missing out on cool stuff like better DLL / 
shared builds and various bits of module cleanup because whoever takes 
on the challenge would have to implement it twice, compatibly, which 
stops being fun.
