[PATCH] D12644: Using -isysroot on Apple platform

[Eric Fiselier via cfe-commits]

You need to use the CMake option `CMAKE_OSX_SYSROOT` to manage the system root because `lib/CMakeLists.txt` uses "CMAKE_OSX_SYSROOT" to find the correct libc++abi.dylib.
Have you tried that? It is unfortunate that Linux and OS X use different options for the same thing though. Maybe we could set `CMAKE_OSX_SYSROOT` internally based on `LIBCXX_SYSROOT`?
