Er... of course this won't work.  The .c file isn't in $(objdir), so it
will never match the pattern $(objdir)/%.c.

You have to use the source directories in the pattern for the .c files.


The idea is to use a prefix that is "above" the source directories.  As
I said above, depending on your environment this might be difficult or
even impossible.
