[PATCH] D37637: [CMake] Determine early on which projects are enabled

[Zachary Turner via llvm-commits]

I'm unable to reproduce this.  Can you try nuking your output directory and
doing a clean build? (re-generate cmake from scratch into an empty
directory)

The only difference between our layouts I can see is that I don't have
compiler-rt checked out, but that shouldn't matter because your first error
involves a dependency from check-all -> lld, and that shouldn't have
anything to do with whether compiler-rt is checked out
