[cmake] mconf builds on Windows

[dschaefer]

Great work with CMake and Ninja! Build times are blazing, especially incremental which was a big issue for Windows.

I do have an issue though. I downloaded the mconf.exe package and added it to my PATH and it runs fine from the command line. When running 'ninja menuconfig' it tries to build mconf and that fails in my environment. Am I missing a step to call the downloaded mconf instead of trying to build it's own?

That's for the report, @dschaefer . This is a legitimate bug, the cmake file isn't correctly looking for mconf on the path before deciding to build it instead. Will fix ASAP.

@dschaefer The commit reference above you should fix mconf for Windows on the cmake branch. Please let us know if it doesn't.

Works great. Thanks! This is going to be fun to work with.
