@gottesmm has been working on this. Deleting the CMakeCache.txt files in the subdirectories of your build directory (llvm-macosx-x86_64 and swift-macosx-x86_64) might make your build go through; if not that then a delete-build-folder clean build. |

Issue Description:
On my machine, utils/build-script -c -x fails with the error "Clang headers were not found" from stdlib/public/SwiftShims/CMakeLists.txt line 65.
Investigation showed that CMAKE_CFG_INTDIR contained xcodebuild-style $(...) variables which were not being substituted before the "if(EXISTS …)" call. The change at <beccadax@2db328fa48d90be530f2fa4cff1034b8bc2dc35d\> corrects this issue for me, although it feels a little hacky and I have zero CMake experience, so there may be a better solution.
