Previously this change was submitted from a Windows machine, so changes made to the case of filenames and directory names did not survive the commit, and as a result the CMake source file names and the on-disk file names did not match on case-sensitive file systems. I'm resubmitting this patch from a Linux system, which hopefully allows the case changes to make it through unfettered. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277213 91177308-0d34-0410-b5e6-96231b3b80d8
