You are making better progress and faster than I am.

I have gone through this sort of process on this project many times
now, and a lot of things occur to me whilst I am doing it. I drag a
folder of sources onto the 'Sources' pane, and then delete the ones
that I do not want.

You should be able to write a short perl or even shell script to give
you the files (or most of them) that define the symbols that ld is
asking for.

Yes, that is the Mac way. It also supports uninstalling by dragging to
the trash.

You seem to be getting there further and faster than I!
