erreur LNK2019: opencv de symbole externe non résolu

J'ai écrit ce programme simple qui charge des matrices de fichiers txt et le calcul des distances.
Lors de la compilation du programme dans visual studio sous windows j'obtiens les erreurs suivantes:

1>main.obj : error LNK2019: unresolved external symbol "void __cdecl cv::fastFree(void *)" (?fastFree@cv@@YAXPAX@Z) referenced in function "public: __thiscall     cv::Mat::~Mat(void)" (??1Mat@cv@@QAE@XZ)

Ce que je fais mal????
