This works. Unfortunately the linker get erros now:

make[2]: *** No rule to make target `/USR/LIB/LIBZ.SO', needed by
`bin/App'.  Stop.

Well, obviously this approach doesn't work. If I use directly
${${package}_LIBRARIES} inside target_link_libraries() these
(lower/mixed case) libraries are not linked (linker error about
unresolved symbols); the parameters for the compiler/linker are missing
(e.g. g++ -lxerces-c doesn't exist).

Cool.


Thanks,
