dict_common is static librarya, oit contains the code common for dict, dictd,
dictfmt and dictzip. While libmaa is shared library. What's the problem?
See below. If you're talking about daily development and paths to libraries,
then use LD_LIBRARY_PATH.

Why? Before building an entire project it is normnally to build
target obj directories. This is not a problem because
I don't create subprojects/subdirectories every day.

This is strained problem.
It is not  a problem to run 'make obj' manually every time
you create new subprojects.

I didn't say I will not call recursive make.
I said that I don't think that recursive make is a problem at all ;-)

What exactly flags?  How about environment variables?

Are you sure?
