opencv неопределенная ссылка на imread с CMake на Windows10 VS Code

Question

Я хочу запустить OpenCV в VS Code IDE с CMake, но он показывает undefined reference to cv::imread().Я пробовал несколько способов (например, редактировать переменные PATH ...), чтобы решить проблему, однако он все еще может ссылаться на библиотеку opencv.

• Вот мой CMakelists.txt

  # cmake needs this line
  cmake_minimum_required(VERSION 2.8)
  
  # Enable C++11
  set(CMAKE_CXX_STANDARD 11)
  set(CMAKE_CXX_STANDARD_REQUIRED TRUE)
  
  # Define project name
  project(cvtest)
  
  # Find OpenCV, you may need to set OpenCV_DIR variable
  # to the absolute path to the directory containing OpenCVConfig.cmake file
  # via the command line or GUI
  find_package(OpenCV REQUIRED)
  
  set(OpenCV_INCLUDE_DIRS "C:/opencv/build/include")
  include_directories(${OpenCV_INCLUDE_DIRS})
  
  # If the package has been found, several variables will
  # be set, you can find the full list with descriptions
  # in the OpenCVConfig.cmake file.
  # Print some message showing some of them
  message(STATUS "OpenCV library status:")
  message(STATUS "    version: ${OpenCV_VERSION}")
  message(STATUS "    libraries: ${OpenCV_LIBS}")
  message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")
  
  # Declare the executable target built from your sources
  add_executable(cvtest cvtest.cpp)
  
  # Link your application with OpenCV libraries
  target_link_libraries(cvtest ${OpenCV_LIBS})
  

• После завершения настроек CMake я запускаю $ cmake -G "MinGW Makefiles".

  -- OpenCV library status:
  --     version: 2.4.13.6
  --     libraries: opencv_videostab;opencv_video;opencv_ts;opencv_superres;opencv_stitching;opencv_photo;opencv_ocl;opencv_objdetect;opencv_nonfree;opencv_ml;opencv_legacy;opencv_imgproc;opencv_highgui;opencv_gpu;opencv_flann;opencv_features2d;opencv_core;opencv_contrib;opencv_calib3d
  --     include path: C:/opencv/build/include
  

• Наконец, я запускаю $ mingw32-make, но вышло с некоторыми ошибками

• Вот cvtest.cpp

  #include <cstdio>
  #include <iostream>
  #include <opencv2/opencv.hpp>
  
  using namespace cv;
  using namespace std;
  
  int main(int argc, char *argv[]) {
      Mat img = imread("lena.bmp", CV_LOAD_IMAGE_COLOR);
      imshow("lena", img);
  }

СделалЯ неправильно понимаю что-то, что я должен знать, и как я могу это исправить?Спасибо!
