If you want to build as x86_64 you should set CMAKE_OSX_ARCHITECTURES to x86_64.

Are you sure all the various libraries you're linking with were also built with the correct deployment target?

You should also try 'lipo -info /path/to/file' to make sure your app/libraries are built for the architecture you expect.

It is not obsolete.  It explains the OS X concepts of deployment and SDK correctly (you appeared to be unfamiliar with them); these concepts have been around for many years.
