1、安装vcpkg

下载

microsoft/vcpkg: C++ Library Manager for Windows, Linux, and MacOS

根目录下执行

bootstrap-vcpkg.bat

设置环境变量

2、安装cmake

Download CMake

3、

新建CMakeList.txt

复制代码

cmake_minimum_required(VERSION 3.10)
project(OpenCVExample)

# 添加可执行文件
add_executable(main testOpencv.cpp)

find_package(OpenCV REQUIRED)

# 直接使用变量而不是目标
include_directories(${OpenCV_INCLUDE_DIRS})
target_link_libraries(main ${OpenCV_LIBS})

testOpencv.cpp

复制代码

#include <opencv2/opencv.hpp>
#include <iostream>

int main() {
    std::cout << "OpenCV version: " << CV_VERSION << std::endl;

    // 创建一个简单的图像
    cv::Mat image = cv::Mat::zeros(400, 600, CV_8UC3);

    // 在图像上绘制文本
    cv::putText(image, "Hello OpenCV!", cv::Point(150, 200),
        cv::FONT_HERSHEY_SIMPLEX, 1.0, cv::Scalar(0, 255, 0), 2);

    // 显示图像
    cv::imshow("OpenCV Test", image);

    std::cout << "Press any key to exit..." << std::endl;
    cv::waitKey(0);

    return 0;
}

build目录下编译：

cmake -DCMAKE_TOOLCHAIN_FILE=E:\vcpkg\scripts\buildsystems\vcpkg.cmake -G "Visual Studio 16 2019" -A x64 ..

cmake --build . --config Release
