fix link order: put zlib after png/tiff/openexr
Previous link dependency: imgcodecs --> zlib --> libpng
this can generate imgcodecs shared lib, until Visual Studio integrated
with vcpkg, which will additionally specify LIBPATH, pointing to vcpkg
installed zlib (if any), which links the wrong zlib.

Fixed link dependency: imgcodecs --> libpng --> zlib
in this fixed case, symbols in zlib referenced in libpng will be found
in the build-from-source static zlib, instead of the vcpkg one.
