Allow generating dmg files thanks to cmake.

A new target is introduced called `dmg`. This must be run explicitly.
Upon running it, it creates the dmg file.

The target respects if we are in a full release or not.

This will officially deprecate the ruby release script in the Xcode
folder upon a successful merge.
