I see.  Well, I just checked my macOS 10.14.1 / Xcode 10.1 bot "RogueResearch12" and indeed it does not have a /usr/include folder.  It is however able to build CMake, VTK, and ITK nightly without any compiler errors.

Perhaps it's not so much a CMake bug as a bug in the project you're trying to build?

Cheers,
