Yep, this is the problem—Swift 3 needs the new beta SDKs now. I forget if there are direct build-script arguments, but you can

1. `sudo xcode-select -s /Applications/Xcode-beta.app` (or wherever the beta is)
2. Delete the CMakeCache.txt files from each build (or just scrap your whole build directory).
3. Reconfigure by rerunning build-script.

You should be able to xcode-select back to your working Xcode after the CMake configuration is complete.
