This part is fine.

This will force it to use the libraries for all your executables.  If 
the --libs option produces only -lXXXX options (and not -Lxxxx) then you 
can put it in a variable like GTK_PKG_LIBS and do this:

TARGET_LINK_LIBRARIES(myexe ${GTK_PKG_LIBS})

If it does include -L options then you can use the STRING command's 
REGEX option to separate the -l and -L options and send the -L options 
to LINK_DIRECTORIES.
