+Subject: [PATCH] [llvm] [cmake] Add additional headers only if they exist
+
+Modify the add_header_files_for_glob() function to only add files
+that do exist, rather than all matches of the glob.  This fixes CMake
+error when one of the include directories (which happen to include
+/usr/include) contain broken symlinks.
