No functional change.
I don't think this is fully right. We did have a separate xcode build, but it was removed a couple of months ago. Instead the regular cmake build supports building a macos-style framework (and I believe it does that regardless of which generator is used). So all that's needed here is to replace references to xcode with some blurb about "frameworks", and instead of "built by llvm" we should just say that we're building with a traditional unix layout. @sgraenitz might know more details here...
