And, in fact, as per that log, it did confuse the configure script, because...

...you *weren't* missing zlib-devel - you were missing the *64-bit version* of zlib-devel.

I have a fix:

        https://code.wireshark.org/review/#/c/22396/

which will cause the configuration process to fail if you can't link with zlib, but the CMake version of the fix found 
a bug in the way we configure libz on Windows, which I filed as bug 13850; that needs to be fixed before I can check my 
fix in.
