It happened for me, I fixed it by forcing Macports to use zlib 1.2.5, instead of 1.2.6 which has introduced the extra issue. The real issue is that we're finding zlib.h in /opt/local/include, but using the libz from /usr. (The Apple supplied version) I tried to find a solution, so that we use one header + library consistently, but didn't yet figure this out. Since zlib doesn't have a subdir in include, we're at mercy of the search paths a little. For the library we can force an explicit absolute path to link against, but Cmake's FindZLIB is finding the one in /usr (correctly, I would say), the problem is the header search order at compile time.
