+Subject: [PATCH] [CMake] Fix libc++abi standalone cmake build.
+
+The cmake files install directory has been changed to
+${prefix}/lib/cmake/llvm since r259821.  Searching cmake modules in
+${prefix}/share/llvm/cmake will result in fatal errors.
+
+This commit fixes the out-of-tree build by changing the CMake module
+search path to: "$(llvm-config --obj-root)/lib/cmake/llvm"
+
+
