1.添加環(huán)境變量
D:\mingw64\bin

2.安裝vscode

3.下載opencv 4.8.0

4.程序引用第三方庫(opencv為例)

打開CMakeLists.txt，引入頭文件，使用include_directories 加入頭文件所在目錄。靜態(tài)鏈接庫link_directories

# 頭文件
include_directories(D:/opencv4.8.0/opencv/build/include)
# 靜態(tài)鏈接庫
link_directories(D:/opencv4.8.0/opencv/build/x64/vc16/lib)

在main 函數(shù)所在文件 添加 #pragma comment(lib,“xxx.lib”),如果當(dāng)前程序是Debug
加 opencv_world480d.lib;否則加opencv_world480.lib

#pragma comment(lib, "opencv_world480d.lib")

5.測試代碼

#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")
# 頭文件
include_directories(D:/opencv4.8.0/opencv/build/include)
# 靜態(tài)鏈接庫
link_directories(D:/opencv4.8.0/opencv/build/x64/vc16/lib)
add_executable(app test01.cpp)
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
