Newbie q. getting started with https://github.com/nianticlabs/spz

Hi, excited to try out the SPZ format. However, my C++ is v.old and rusty. I’ve pulled the code from github and built the ZLib dependency. However, when I compile I’m faced with

1>load-spz.obj : error LNK2019: unresolved external symbol deflate referenced in function "bool __cdecl spz::`anonymous namespace'::compressGzipped(unsigned char const *,unsigned __int64,class std::vector<unsigned char,class std::allocator<unsigned char> > *)" (?compressGzipped@?A0xa46d448a@spz@@YA_NPEBE_KPEAV?$vector@EV?$allocator@E@std@@@std@@@Z)

Sorry for the C++ newbie question but any pointers would be welcome.

My dumb mistake, I’d configured the path to zlib incorrectly
