When CMAKE_SYSTEM_PROCESSOR isn't set, crosscompilation for iOS fails because required .cpp files are not found.
CMAKE_SYSTEM_PROCESSOR isn't used by Apple as their toolchains use only CMAKE_OSX_ARCHITECTURES which is a list of architectures.
It doesn't look like this CMake supports Apple's universal builds, so I've made logic that if we are building only for one architecture we set CMAKE_SYSTEM_PROCESSOR to CMAKE_OSX_ARCHITECTURES, and if its trying to build universal build we fail with a message.
