1) You should use your package manager on Archlinux and your own installation on Windows. Do not rely on the Qt third-party installation. It may be there today, but disappear at any certain moment when a new release comes out.

This is what I would suggest you doing on your Archlinux box:

pacman -S zlib

2) Also, you should use FindZLIB.cmake for finding zlib the following way in your CMakeLists.txt:

find_package( ZLIB REQUIRED )
if ( ZLIB_FOUND )
    include_directories( ${ZLIB_INCLUDE_DIRS} )
    target_link_libraries( YourProject ${ZLIB_LIBRARIES} )
endif( ZLIB_FOUND )
