Yes, no problem.  I'll add them.

The reason you had problems with zlib is because the newer form of the 
FIND_LIBRARY command that allows multiple names needs to be used.  This:

FIND_LIBRARY(ZLIB_LIBRARY z
   /usr/lib
   /usr/local/lib
)

should be

FIND_LIBRARY(ZLIB_LIBRARY
   NAMES z zlib
   PATHS /usr/lib /usr/local/lib
)

and since the FIND_LIBRARY command uses CMAKE_LIBRARY_PATH automatically 
your problem should be solved.
