win10+clion+opencv配置出错undefined reference to cv::imread未定义引用

这个错误的原因一般是因为在Cmake文件中没有设置对Opencv库的引用所造成的，因此需要在CmakeLists.txt文件中添加一句 

set(Opencv_LIBS opencv_core opencv_imgproc opencv_highgui opencv_imgcodecs)，一般即可处理大多数错误。

修改后的Cmake配置文件：

cmake_minimum_required(VERSION 3.24)
project(untitled)

set(CMAKE_CXX_STANDARD 17)

set(OpenCV_DIR "编译后的Opencv/install路径")
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})

#添加执行程序
add_executable(untitled main.cpp)

#添加
set(Opencv_LIBS opencv_core opencv_imgproc opencv_highgui opencv_imgcodecs)
#连接库
target_link_libraries(untitled ${Opencv_LIBS})
