title: How to create tasks for a VSCode workspace
body: <p>I am developing some embedded code using VSCode as my IDE. I have created a workspace and I have two projects in it. When I have only a single project I can create my build and launch files, however, what I would like to do is to have build tasks and launch configurations for the whole workspace.</p>
  <p>I have tried to manually create a &quot;.vscode&quot; folder in the workspace and added a tasks.json to it. However, when I select build VSCode is not presenting the tasks in the tasks.json file as options. It says there are no build tasks defined.</p>
  <p>The VSCode documentation seems to suggest it is possible to have workspace-level build tasks, however I have failed to find how to configure those.</p>
