In the systems that I've hacked on, the rule has been "directories and
libraries are cheap: separate sources (and objects) into a directory
per library or program".  Cross-directory references are best done via
-I and -L and never via ../whatever references.

With that, CFLAGS assignments and similar can be done on a per
directory basis, whether via a Makefile per directory (where a
recursive make setup is used for whatever reason) or via a
${OBJDIR}/%.o: ${SRCDIR}/%.c rule for each OBJDIR:SRCDIR pair.
