Sometimes, desire to use an object file in multiple directories arises. Assume the following directory structure.

• src/common/tests
• src/unittest

A test in common/tests need only one object in unittest to be linked, but one does not want to make it as a library for that.

Assume the following directory structure.

• src
• src/common
• src/common/tests

Of course, common/tests includes common for testing. Problem is when one wants to include common/tests from common, say, to make tests runnable from common directory. Simply SubIncludeing each other result in infinite recursion, and does not work .
