Comment:
> I think it's better to patch their Makefile to have let's say -include config.mk and put the option there. Whoever want some custom option could put the config into files directory. With that approach, we won't need to care for nnn's change in build option whatsoever. As for build dependencies, just add them all. nnn is always a leaf (as in graph) packages.

Here is possible implementation:
