title: Intellij highlighting not existing errors, thinking that LWJGL is not imported
body: <p>I imported LWJGL to the libs folder inside the project. The application works fine, but Intellij is highlighting almost every line, thinking that lwjgl is not imported.

  <p>Is there any simple solution? I want to avoid importing the library another way. </p>
