With the above Makevars and the correct 'Depends' line in your package description (again, see the skeleton), you won't have to muck about with compiler switches and lookup paths, and everything should 'just work'.

Yes, I'm doing it by hand since I'm still coding.  I compile after
some progress to make sure everything is OK.

Let's say I place the my code in in /src.  Do I HAVE to turn this into
a package in order to compile?  Or is there a way to compile from
here.  Sorry I'm new at this approach.
