title: Is it possible to set a task.json for all c++ files in VSCode?
body: <p>I'd like to give VSCode a try.
  Is it possible to set compile and build commands for all .cpp files? Just like in Geany? And it is possible to do that for every supported language?</p>
  
  <p>Searching here and there it seems that I have to set it in task.json for each project (even the link to iostream)</p>
