I try but cmake give me an error:

The C compiler identification is unknown The CXX compiler identification is unknown CMake Error in CMakeLists.txt: No CMAKE_C_COMPILER could be found.

CMake Error in CMakeLists.txt: No CMAKE_CXX_COMPILER could be found.

CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as

cmake_minimum_required(VERSION 3.7)

I downloaded the opencv_contrib.zip and unpack it. Is not the correct way?

It dosen't work. In the folder of opencv_contrib there isn't any file.lib. It's possible?

HI, I'm new in VS2015 and in Opencv_contrib. I'm trying to make a face recognition program using the cv::face::FaceRecognizer. In fase of compilation it gives me the following error:

1>FaceRecognition.obj : error LNK2019: unresolved external symbol "public: int __cdecl cv::face::FaceRecognizer::predict(class cv::_InputArray const &)const " (?predict@FaceRecognizer@face@cv@@QEBAHAEBV_InputArray@3@@Z) unresolved in function main 1>FaceRecognition.obj : error LNK2019: unresolved external symbol "struct cv::Ptr<class cv::face::basicfacerecognizer=""> __cdecl cv::face::createEigenFaceRecognizer(int,double)" (?createEigenFaceRecognizer@face@cv@@YA?AU?$Ptr@VBasicFaceRecognizer@face@cv@@@2@HN@Z) unresolved in funciont main

I know there is a problem this the linker and probably I fortgot to include some file.lib but I do not know which. Please, someone can help me?
