title: How to enable C++17 support in VSCode C++ Extension
body: <p>I keep on getting error squiggles on std::string_view, but I am able to build just fine. Is there a way to tell intellisense or the C++ linter to use C++17?</p>
  
  <p>The specific error I get is:</p>
  
  <pre><code>namespace "std" has no member "string_view"
  </code></pre>
