title: Does vscode use workspaceRoot or workspaceFolder?
body: <p>I have been recently trying to use the MinGW gcc compiler with Code, and am getting some issues with Intellisense(not breaking, but I find it annoying). </p>
  
  <p>I followed the documentation to edit the path for the c_cpp_properties.json file, but the error continues to pop up and I think I have also found contradictory information. </p>
  
  <pre><code>   {
          "name": "Win32",
          "includePath": [
              "${workspaceRoot}"
          ],
          "defines": [
              "_DEBUG",
              "UNICODE"
          ],
          "intelliSenseMode": "msvc-x64",
          "browse": {
              "path": [
                  "${workspaceRoot}",
                  "C:\\MinGW\\lib\\gcc\\mingw32\\6.3.0\\include\\c++"
              ],
              "limitSymbolsToIncludedHeaders": true,
              "databaseFilename": ""
          }
      }
  ],
  "version": 3
  </code></pre>
  
  <p>I looked on the github repo for the documentation and found someone had committed a change where ${workspaceRoot} was changed to workspaceFolder in the documentation. However, root seems to be the default for VS code, and I only updated to the new orange logo version this morning. </p>

  <p>So which is the correct way to get Intellisense working, Folder or Root? </p>
