If it were so, it wouldn't be that hard to explain, how the stuff works,
my colleagues would've read it in the manual instead.

Now do the same, except link it statically.
Feel the difference.

And, try it without setting MAKEOBJDIRPREFIX and running "make obj"
for the whole tree.
Don't create objdir for "dict" and create it for "dict_common".
This is valid usage, but your build fails.

Now tell us, how are you going to build those libraries you depend on
without calling recursive make?
How are you going to pass flags to you recursive make?

You don't understand the problem.
