[webkit-dev] CMake on Windows

[Alex Christensen]

I plan to switch build-webkit --wincairo to use CMake in the near future.  We are not ready to remove the Visual Studio build system yet and won’t be for a while, but a bot using CMake on Windows will help us notice if anything breaks as we make more progress.  Building from Source/WebKit/WebKit.vcxproj/WebKit.sln should be unaffected.  I think I’m the only one with a WinCairo build bot, but please let me know if this will cause a problem for anyone.
