1.添加环境变量
D:\mingw64\bin
2.安装vscode
3.下载opencv 4.8.0
4.程序引用第三方库(opencv为例)
打开CMakeLists.txt,引入头文件,使用include_directories 加入头文件所在目录。静态链接库link_directories
# 头文件
include_directories(D:/opencv4.8.0/opencv/build/include)
# 静态链接库
link_directories(D:/opencv4.8.0/opencv/build/x64/vc16/lib)
在main 函数所在文件 添加 #pragma comment(lib,“xxx.lib”),如果当前程序是Debug
加 opencv_world480d.lib;否则加opencv_world480.lib
#pragma comment(lib, "opencv_world480d.lib")
5.测试代码
#include <opencv2/opencv.hpp>
#include <iostream>
#pragma comment(lib, "opencv_world480d.lib")
using namespace cv;
using namespace std;
int main(int argc, char** argv) {
Mat src = imread("D:/Work/opencv_test/images/1.jpeg");
if (src.empty()) {
cout << "could not load image..." << endl;
return -1;
}
imshow("input", src);
waitKey(0);
return 0;
}
CMakeLists.txt
cmake_minimum_required(VERSION 3.28.0)
project(cpp_test)
# 头文件
include_directories(D:/opencv4.8.0/opencv/build/include)
# 静态链接库
link_directories(D:/opencv4.8.0/opencv/build/x64/vc16/lib)
add_executable(app test01.cpp)
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
