I do not find the zlib patched files. BTW, I have installed IPP 2017 Update 1. So where can I find them?
Look in <IPP directory>/components/components_and_examples_win(lin)_ps.zip(this is archive)/components/interfaces/ipp_zlib.
There are patch files and readme.html describing patch and build procedures.
For more complete information about compiler optimizations, see our Optimization Notice.
