title: Unresolved Inclusion: Eclipse Not Showing "Includes" tab under "Paths and Symbols":
body: <p>I am trying to resolve some inclusions in Eclipse. Normally I click on project properties, then 'C/C++ General', then 'Paths and Symbols', then start adding include directories, as is shown here:

  <p>But today, for some strange reason, Eclipse (Juno) is not showing the includes tab!<img src="https://i.stack.imgur.com/6Fd0A.png" alt="My version of eclipse."> </p>
  
  <p>How can I get the 'Includes' tab back so I can resolve the symbols in my project?</p>
