ofxHTTP / Windows / Linker 2019/2001 Error

Hi there, I’m trying to get the ofxHTTP addon to work. It added the depedencies ofxMediaType/ofxIO/ofxSSLManager and the ofxNetworkUtils but ending up with a lot of LNK2019 and LNK2001 errors.

Error	LNK2019	unresolved external symbol "public: __thiscall ofx::HTTP::IPVideoRouteSettings::IPVideoRouteSettings(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,bool)" (??0IPVideoRouteSettings@HTTP@ofx@@QAE@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@_N@Z) referenced in function "public: __thiscall ofx::HTTP::SimpleIPVideoServerSettings::SimpleIPVideoServerSettings(void)" (??0SimpleIPVideoServerSettings@HTTP@ofx@@QAE@XZ)	CCV2015	C:\Users\Boss\Desktop\of_v0.9.8_vs_release\of_v0.9.8_vs_release\apps\myApps\CCV2015\main.obj	1	

Any hints on were to start looking for errors?
