Paf,

If I understand you correctly, you mean to say that in the top level
CMakeLists.txt, if I SET(CMAKE_INCLUDE_CURRENT_DIR ON) and
INCLUDE_DIRECTORY(.) then all other subdirectories I add will all
automatically include the other directories?

This however, is not the behavior I am observing. Setting
CMAKE_INCLUDE_CURRENT_DIR does not seem to have any effect.
