'llvm/Support/Casting.h' file not found

[LarryRen]

MacOS 10.13
XCode 9.1(9B55)

Git clone the project and llvm+clang(put them under the project dir too). All settings are just included in the project already. No need to change anything. Then I got the error 'llvm/Support/Casting.h' file not found.

The Casting.h can be found under "libclang-experiments/llvm/include/llvm/Support/Casting.h". I just got no way to include it correctly.

I have the same issue with you，just change the header search path from “$(SRCROOT)/llvm/tools/clang/include (Resursive)“ to "$(SRCROOT)/llvm (Resursive)", then you can build it successfully.
