And if compatibility with CMake < 2.4.4 isn't a concern, an even better way
to do this is:
# set this at your topmost CMakeLists.txt
set(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true)
if(ZLIB_FOUND)
message("HAVE system zlib")
else()
message("NO system zlib")
endif()
P.S.
The WARNING option to message() is new to CMake 2.8. For
better compatibility with CMake 2.6 and lower, simply omit it which should
give you a similar effect.
