That means ZLIB requires a wrapper to correctly set that value on Linux. You are just dropping a droplet of water on a hot stone with that patch. You might have fixed freetype but all other ports using
ZLIB_LIBRARIESstill have the same problem. The root cause ist thatZLIB_LIBRARIESis not correctly set with debug/optimized keywords and needs fixing on Linux/OSX.There was a problem hiding this comment.

This means that all module modes(
Find*.cmake) that call cmake by default have a high probability of this problem. So I think we should deal with it uniformly (by vcpkg, not by port).
