vscode配置c++的opencv环境

好的，以下是配置步骤：

1. 安装 Visual Studio Code 和 C/C++ 扩展
2. 下载 OpenCV 并解压到某个目录下
3. 在 VS Code 中打开一个 C++ 文件，按下 Ctrl + Shift + P，输入 "C/C++: Edit Configurations (JSON)" 并选择它
4. 在打开的 launch.json 文件中添加以下配置：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "g++ - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
            "preLaunchTask": "C/C++: g++ build active file",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
                    "description": "Set path to opencv libraries",
                    "text": "-environment-cd ${workspaceFolder}/opencv/build",
                    "ignoreFailures": true
                },
                {
                    "description": "Set path to opencv libraries",
                    "text": "-environment LD_LIBRARY_PATH=${workspaceFolder}/opencv/build/lib",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

5. 在 setupCommands 中添加以下两个命令，以设置 OpenCV 库的路径：

{
    "description": "Set path to opencv libraries",
    "text": "-environment-cd ${workspaceFolder}/opencv/build",
    "ignoreFailures": true
},
{
    "description": "Set path to opencv libraries",
    "text": "-environment LD_LIBRARY_PATH=${workspaceFolder}/opencv/build/lib",
    "ignoreFailures": true
}

6. 在 VS Code 中打开一个 C++ 文件，按下 F5，选择 "g++ - Build and debug active file"，然后按下回车键即可开始调试。
