I am not holding my breath on cmake. Until we have something pretty
solid on that front I'm going to assume it's not happening. If we're
going to support VS2015 (and I think we should) then it should be
supported for all live branches if possible. I'm assuming the changes
would be pretty localized, at least in src/tools/msvc, and adding a new
compile shouldn't break anything with existing compilers.
