I don't think helper libraries are needed here, that's mainly a local library that's linked from the projects sources files and not necessarily another project. I've used a helper library for some projects where you have two executables which share some of the same classes, for instance. 

 have only used them for building another project's sources in Pd actually, not port midi and port audio, mainly to avoid their relatively slowly maintained configure scripts.

Just run install_name_tool after building with the relevant options and files, probably via a secondary makefile target. You may need to read up on how makefiles work and the pd-lib-build docs on how the build steps are performed to find the right place to add it.*
