MacOS has @executable_path which is the same as $ORIGIN.  See:

https://wincent.com/wiki/%40executable_path%2C_%40load_path_and_%40rpath

Unfortunately on MacOS they have "applications" which are much more
complicated and can have frameworks etc.  But I think @executable_path
is pretty close to exactly the same thing as $ORIGIN and works fine if
you're just building a normal application.
