The CMakeLists file for the static zlib checks for presence of
unistd.h, but it doesn't properly define HAVE_UNISTD_H if it's found.
This change adds the necessary preprocessor definition if unistd.h is
found.
Upstream zlib handles this with by configuring zconf.h with CMake:
cacf7f1d4e/zconf.h.cmakein (L11)
Dolphin's static version of zlib doesn't do this, which is why setting
Z_HAVE_UNISTD_H in zlib's CMakeLists.txt isn't enough.
This probably wasn't noticed since because most *nix systems will use
the shared zlib. Force use of the static zlib (comment out
find_package(ZLIB) in the root CMakeLists.txt) and you'll see implicit
function declaration warnings during its compilation.
"Version 1.2.5 fixes bugs in gzseek() and gzeof() that were present in version 1.2.4 (March 2010). All users are encouraged to upgrade immediately."

- various fixes for using CMake on Windows
- support building external SDL, zlib, CLRun, wxWidgets
- support using precompiled GLew and WiiUse libs on Windows
For what it's worth, I'm not quite sure if I got all the wx files right...
Building with MSVC2008 still doesn't work yet, but is a lot closer now.
