Hello, I have to use vs2010 and opencv3.1 for testing purpose.

I cmaked a project and build it with my visual studio. Now I'd like to write a short program to test it. Sadly it does not work when creating. this is my code:

Mat image;
image = imread(argv[1], IMREAD_COLOR); // Read the file

if(! ) // Check for invalid input
    cout << "Could not open or find the image" << std::endl ;
    return -1;

namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.
imshow( "Display window", image ); // Show our image inside it.

waitKey(0); // Wait for a keystroke in the window
return 0;


#include "stdafx.h" #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/calib3d/calib3d.hpp> #include <opencv2/imgproc/imgproc.hpp> #include <opencv2/video/video.hpp> #include <iostream>

And the error:

opencv-test2018.obj : error LNK2001: Nicht aufgelöstes externes Symbol ""class cv::Mat __cdecl cv::imread(class cv::String const &,int)" (?imread@cv@@YA?AVMat@1@AEBVString@1@H@Z)
C:\Users\Visual Studio 2010\Projects\opencv-test2018\x64\Release\opencv-test2018.exe : fatal error LNK1120: 1 nicht aufgelöste externe Verweise.'

I added the linker setting to:


there are all the .lib inside. I added the following


which are all located inside. I have set my VS to x64 Release

Any idea why i can not create the project?
