If you have in one CMakeLists.txt:

PROJECT( FOO )
ADD_LIBRARY( fooLibrary source.cpp )

then you can simply do in another CMakeLists.txt:

INCLUDE_DIRECTORIES( ${FOO_SOURCE_DIR} )
# "FOO" here comes from the PROJECT() line in the other CMakeLists.txt

I've seen your English improve a lot over the last half year, so I would not 
be sorry for that :-) Anyway, I'd guess it's at least about half (2/3?) the 
world that doesn't speak English natively.
