OpenCV 3.2.0, Visual Studio 2015, Windows 7

I installed the pre-built libraries OpenCV 3.2.0 on Windows 7 following the instructions here and I am encountering errors when trying to use them in Visual Studio 2015.

The variable OPENCV_DIR is set correctly: 

C:\>echo %OPENCV_DIR%
C:\OpenCV\Build\x64\vc14

C:\>dir %OPENCV_DIR%
 Le volume dans le lecteur C s'appelle OS
 Le numéro de série du volume est 1234-ABCD

 Répertoire de C:\OpenCV\Build\x64\vc14

27/01/2017  17:10    <REP>          .
27/01/2017  17:10    <REP>          ..
27/01/2017  17:11    <REP>          bin
27/01/2017  17:10    <REP>          lib
               0 fichier(s)                0 octets
               4 Rép(s)  19 236 450 304 octets libres

And the rules for the project are like there

With the libraries specified as

enter image description here

opencv_calib3d320d.lib
opencv_core320d.lib
opencv_features2d320d.lib
opencv_flann320d.lib
opencv_highgui320d.lib
opencv_imgcodecs320d.lib
opencv_imgproc320d.lib
opencv_ml320d.lib
opencv_objdetect320d.lib
opencv_photo320d.lib
opencv_shape320d.lib
opencv_stitching320d.lib
opencv_superres320d.lib
opencv_ts320d.lib
opencv_video320d.lib
opencv_videoio320d.lib
opencv_videostab320d.lib

But when I try to compile the basic test project written there 

#include <opencv2/core.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main( int argc, char** argv )
{
    if( argc != 2)
    {
     cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
     return -1;
    }
    Mat image;
    image = imread(argv[1], IMREAD_COLOR); // Read the file
    if( image.empty() ) // 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;
}

I get the error

1>------ Build started: Project: ImageCorrection, Configuration: Debug x64 ------
1>  test.cpp
1>LINK : fatal error LNK1104: cannot open file 'opencv_calib3d320d.lib'
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I am really new to compilation and linking on Windows and Visual Studio (I am used to g++ on Linux) so I really have no idea of what I am doing wrong here.
I think that it might have something to do with the dynamic linking, but I do not know neither how to investigate nor how to solve it.

Ant help is most appreciated! :D

OpenCV 3.2 prebuild binaries have just the world lib:

  • opencv_world320.lib for release
  • opencv_world320d.lib for debug

That's all you need to link.
