I always get errors in linker with Visual Studio 2019 and OpenCV

Question

I installed OpenCV-v2.4.11 from NuGet Package Manager in Microsoft Visual Studio 2019. However, I can't get working this code:

#include <opencv2/opencv.hpp>

int main()
{
    cv::Mat A;
    return 0;
}

I got these errors:

Errors once more: (Visualisation is name of my project)

As john wrote in a comment below the question:

Visual Studio can show you the linker command line. Right click the project and pick properties. Then navigate to Configuration Properties/Linker/Command Line. Compare the command lines of the project that works and the one that doesn't, there must be a difference somewhere.
