win10 VS Code配置 C++ opencv环境

具体关于mingw,cmake之类的下载配置见：
写的很详细了，注意看完（一）后还有（二）

我这里就写下配置json文件的结果（搞了几个小时才搞定）。

总之就一句话： 一定要使用default生成的json文件来改！！！

不要从各种博客上借鉴改来改去，每个人的vscode版本都不一样，default生成的json文件都不一样，其实需要改的地方很少，只需要在task.json和c_cpp_properties.json上加上路径即可；

首先是launch.json

这个不需要修改，在一个文件夹内open with vscode后会自动生成.vscode文件，然后新建一个.cpp文件，debug就会自动生成launch.json，完全不需要修改，用default的配置即可；

（如果需要显示powershell窗口输出的话，可以设置 “externalConsole”: true,
这里默认是false）

接下来是task.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe build active file",

            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                // 从这里开始修改，改成自己的路径
                "-I",
                "D:/Software/open-cv/opencv/build/include",
