ubuntu vscode配置opencv环境

• 1.下载安装包

• 2.编译opencv

• 3.launch.json文件

（左侧带小虫子的按钮）debug--open configuration--c++(GDB/LLDB)

• 4.task.json文件

快捷键ctrl+shift+p打开命令行，输入Tasks: Run task，会出现如下提示：
No task to run found. configure tasks...
回车，然后依次选择如下：
Create tasks.json file from template
Others Example to run an arbitrary external command.

• 5.c_cpp_properties.json文件

ctrl+shift+p-->edit configurations(json)-->修改c_cpp_properties,json文件
