LGTM. We want to use vcpkg's zlib, and we have correct wrapper. It just doesn't deal with these evil suffix hacks.

However, there is always a more minimal patch: Add

elseif(1)
  find_package(ZLIB REQUIRED)

before the else(), and leave the remainder unchanged.

[cenit]

agree with @dg0yt for minimal patch.
same patch should be done also for opencv3
