title: C++17 support Eclipse Neon
body: <p>I read <a href="https://isocpp.org/std/status" rel="noreferrer">here</a> that C++17 is feature-complete although the specifications are not completely ready yet. How can I use C++17 features in my code, especially in Eclipse CDT (Neon)?</p>
  
  <p>Specifically, I would like to use the <code>filesystem</code> to be able to iterate over directories easily.</p>
