title: Visual Studio Code, #include <stdio.h> saying "Add include path to settings"
body: <p>I'm trying to build C/C++ in Visual Studio Code. I installed C/C++ and all the relevant extensions.</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  int main() {
      printf("Test C now\n");
      return 0;
  }
  </code></pre>
  
  <p>But there's a green line under <code>#include &lt;stdio.h&gt;</code> saying "Add include path to settings". When I click it, it moves over to "c_cpp_properties.json".</p>
  
  <p>How and where can I add include paths in the configurations below?</p>
  
  <pre><code>"configurations": [
      {
          "name": "Mac",
          "includePath": ["/usr/include"]
      }
  ]
  </code></pre>
