Review comment:
As far as I can tell, it's because Xcode selects whether to build in
debug or release mode after configuration, so if it's not set then it will
succeed building in Release but not in Debug because it'll try to find
`libgtest.dylib` instead of `libgtestd.dylib`. Without this change, if I
specified `-DCMAKE_BUILD_TYPE=Debug`, Xcode would be able to build in debug
mode but not release mode.
