But if in YOURLIB1 I do 
TARGET_LINK_LIBRARIES(YOURLIB1 YOURLIB2)

then in YOUR_EXE_TARGET I only need to do
TARGET_LINK_LIBRARIES(YOUR_EXE_TARGET YOURLIB1)

So, in one hand, I don't need to know that YOURLIB1 needs YOURLIB2.
OTHO, I have to know, because of the include files... Taking headers files 
into account, the sample above will be

For YOURLIB1:
INCLUDE_DIRECTORIES( YOURLIB2_DIR )
TARGET_LINK_LIBRARIES( YOURLIB1 YOURLIB2 )

For YOUR_EXE_TARGET:
# Here I have to include YOURLIB2_DIR
INCLUDE_DIRECTORIES( YOURLIB2_DIR YOURLIB1_DIR )
TARGET_LINK_LIBRARIES( YOUR_EXE_TARGET YOURLIB1 )



What I said is correct, isn't it?
