First part of supporting CMake under Windows - this is WIP, and if you want to work on it, be on IRC.

This is NOT a complete product, but we need all hands on deck to get this sorted out ASAP, and as such we throw it in.
No changes are done to Windows buildmethods untill this is -completed- and -working-.
