我想在带有CMake的VS Code IDE上运行OpenCV，但它显示for。我已经尝试了几种方法（例如，编辑PATH变量...）来解决该问题，但是它仍然可以链接到opencv库。
这是我的undefined reference to cv::imread()
CMakelists.txt完成CMake设置后，我运行# 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})
。
$ cmake -G "MinGW Makefiles"最后，我运行 -- 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
，但是它出了一些错误

cvtest.cpp我是否误解了一些我应该知道的东西，我该如何纠正？谢谢！
