响应式网站公司做网站需要自备服务器吗

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)set(CMAKE_GENERATOR "MinGW Makefiles")
# 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)
