Setting object directory inside projects's Makefile is just wrong way
to do development. This makes Makefiles full of %^&*^%%
OBJDIR should be set outside projects's Makefile, e.g.
in your mk.conf based on PROG or somewhere in Makefile.in
or in user's (developer's) environment.

Anywhere but not in project's Makefile.

Just separate project's "core" from developer's "preferences".

Your colleagues are offtopic. Lots of my colleagues use windows and
don't know anything about make at all. So what?
