Thanks for your replay. But no, this doesn't work. This goes along with 
what Alex just wrote back - include_directory behaves like normal 
variables. Setting

INCLUDE_DIRECTORIES(  "${CMAKE_CURRENT_BINARY_DIR}" )

just works for the directory you're currently at and the directories 
beneath it - but not for those above or on the same level.
