compile appear LNK2001 "public: __thiscall cv::Exception::Exception

[jackweiwang]

I compiled under vs2015 and then imported openFramework and ofxFaceTracker and ofxCv after the compiler has the following problems

严重性 代码 说明 项目 文件 行 禁止显示状态
错误 LNK2001 无法解析的外部符号 "public: __thiscall cv::Exception::Exception(int,class std::basic_string<char,struct std::char_traits,class std::allocator > const &,class std::basic_string<char,struct std::char_traits,class std::allocator > const &,class std::basic_string<char,struct std::char_traits,class std::allocator > const &,int)" (??0Exception@cv@@QAE@HABV?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@std@@00h@Z) FaceTracker C:\of_v0.9.3_vs_release\examples\3d\FacePrimitivesExample\Wrappers.obj 1

When the compiler does not appear error

Excuse me, why is this ?
