mingw32-make.exe [3]: *** Ошибка 1 [CMakeFiles \ myAnswerCpp.dir \ build.make: 102: myAnswerCpp.exe]

Я использовал vscode, cmake для компиляции проекта opencv в Windows. У меня была проблема при сборке. Я очень смущен.

Ранее была ошибка, потому что OpenCV не был завершен. После полной сборки я изменил свой CMakeLists.txt, с set(OpenCV_DIR D:/OpenCV/opencv/sources/build) на set(OpenCV_DIR D:/OpenCV/opencv/build/x64/vc15/lib). Но есть некоторые новые ошибки.

Это мой CMakeLists.txt 

PROJECT(myAnswerCpp)
cmake_minimum_required(VERSION 3.5)
set(OpenCV_DIR D:/OpenCV/opencv/build/x64/vc15/lib)
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable(myAnswerCpp myAnswerCpp1.cpp)
link_directories(${OpenCV_LIBRARY_DIRS})
target_link_libraries(myAnswerCpp ${OpenCV_LIBS})

И это мой тестовый код. 

#include <iostream>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main(){
    Mat src = imread("C:/Users/87689/Desktop/bit.JPG", IMREAD_COLOR );
    imshow("bit",src);
    waitKey(0);
    return 0;
}

И это выходная информация

Пожалуйста, помогите мне решить ошибки. Большое спасибо!
