compile source errors

[gibroni]

Havent updated my server in months and seen there was new navmesh stuff added, so I am trying to recompile a new source. But am receiving three errors causing zone.vcxproj failed.

\zone\map.cpp(999): error C3861: 'InflateData': identifier not found
\zone\map.cpp(1055): error C3861: 'EstimateDeflateBuffer': identifier not found
\zone\map.cpp(1059): error C3861: 'DeflateData': identifier not found

Im sure someone smarter then me can tell me whats going on for me?

using new cmake, new boost 1.67 and vs studio 17.
