配置好CMakeLists.txt
运行代码

#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;//包含cv命名空间

int main() {
    std::cout << "Hello, World!" << std::endl;
    Mat img = imread("F:\\test.png");//imread()函数载入图像
    //从文件中读入图像，注意图像路径最好不要用相对路径，因为CLion生成的exe不在当前目录下。
    if(img.empty())
    {
        fprintf(stderr, "Can not load image\n");//如果读入图像失败，返回错误信息
        return -1;
    }
    //显示图像
    imshow("image", img);//imshow()函数显示图像
    waitKey();//此函数等待按键，按键盘任意键就返回
    return 0;

在
的Environment variables:中添加PATH=F:\ProgramFiles\opencv3\opencv\MinGw64_build\install\x64\mingw\bin
此目录是由cmake-gui.exe编译得到的

opencv安装编译参考链接：https://fanfuhan.github.io/2019/03/19/opencv_Clion/

所需环境
MinGw + Cmake + Clion + opencv

安装MinGw
参考：install MinGw

安装Cmake
参考：install Cmake

Cmake下载网址：Cmake download

注：Cmake最好安装跟Clion中配置一样的版本，省的麻烦

安装 opencv
下载地址 ：opencv download

解压到 opencv4文件夹中

解压后：

配置环境变量：

Clion 配置

编译opencv源码
打开Cmake-GUI，选择源码路径和输出路径

点击Configure，选择MinGW Makefiles，点击Finish，开始编译

等待一段时间后，会有很多报红，再次点击Configure，红色消失，点击Generate

进入输出目录，在cmd 运行下面代码，等待完成

mingw32-make -j8

运行mingw32-make install，等待片刻，输出目录下会多出install文件夹

添加…\install\x64\mingw\bin 添加到path系统环境变量环境变量

编辑CMakeLists.txt

cmake_minimum_required(VERSION 3.13)
project(learnOpencv)
set(CMAKE_CXX_STANDARD 11)
set(OpenCV_DIR “D:\software\opencv4\MinGW64_build\install”)
set(CMAKE_MODULE_PATH $CMAK{E}_{M}ODUL{E}_{P}ATH"${CMAKE_SOURCE_DIR}/cmake/")
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable(learnOpencv test.cpp)
set(OpenCV_LIBS opencv_core opencv_imgproc opencv_highgui opencv_imgcodecs)
target_link_libraries(learnOpencv ${OpenCV_LIBS})

注意：opencv4必须要c++11支持
测试
#include <opencv2\opencv.hpp>
using namespace cv;
int main()
{
Mat img = imread(“D:\code-workspace\Clion-workspace\learnOpencv\images\1.png”,WINDOW_AUTOSIZE);
namedWindow(“刘亦菲”);
imshow(“刘亦菲”, img);
waitKey(0);
return 0;
}
