Depends on what you add, but for the most part, yes, I agree that is likely.

That was background not a question. I managed that part. (I think it
was from the zipped make tutoral suggested by the man page or ports).

That is exactly what I was looking for. Thank you.

Roughly speaking, under src/, I had backends/[SHLIB_NAME]/,
frontends/[BIN_NAME], objs/, and include/. I wanted to build
everything into objs/, that way I only needs the ldflags to have
"-L../../objs", rather than "-L../foo -L../bar", where foo and bar
vary from app to app.
