[PD] linking libs in extern development

[david medine]

Dear folks,
Does anybody know a good way to link libraries in a Pd extern build? I 
am using plain ol' command line and makefiles. It would be nice to be 
able to do this without modifying the Makefile in the 
Pd.etc./Contents/Resources/ directory, but due to my general ignorance 
of programming lore, I don't really know how to do this. Any suggestions?
Thanks,
David Medine
