Qt OpenCV programm exits with code -1073741515 - c++

Question

What i want to do
I try to use opencv and run a short example program.
Problem
It exits with code -1073741515. I never managed to use openCV on any of the 4 systems i tried, so i do something wrong but don't know what.
I had diffrenet errors using different attempts (undefined reference, crashing programm without error code, etc.), this here is the just simplest example.
What i figured out
Another post told me, that -1073741515 is equal to 0xC0000135 meaning STATUS_DLL_NOT_FOUND.
What i tried
The programm crashes, if include #include <opencv2/core/core.hpp>,
#include <opencv2/highgui/highgui.hpp>and
#include <opencv2/imgproc/imgproc.hpp>. When i comment them out, it runs wnd returns 0 as intended. I don't even need to use anything like cv::Mat or something to make it crash. That seems strange, because the code completion suggests me stuff from openCV, so it somehow sees it. Including #include <opencv2/opencv.hpp> instead leads to the same error code. Including something beginning with opencv (not opencv2) works, for example #include <opencv/cv.hpp>, but has not enough functionality.
Source file
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <iostream>
using namespace std;
int main()
{
cv::Mat InputImage = cv::imread("C:/Users/Public/Pictures/Sample Pictures/Chrysanthemum.jpg");
if(!InputImage.empty())
cv::imshow("test", InputImage);
else
cout << "imgage is empty" << endl;
return 0;
}

Answer 1

As Jiu pointed out in the comment above, the solution was simple:
Copy the .dll not the .lib and it works.
