Whenever you go out into beta/alpha/preview/pre-release territory, you're setting yourself into a world, where you're mostly alone. For instance if you'd get a pre-release console for developers you wouldn't expect to play all kinds of AAA titles on it, or would you?
So as said by Jebbs, either build it yourself or get to a version that's officially released. Also keep in mind that CMake might not support VS 2013 yet, so you might have to convert old project file versions or try the NMake make files.
