title: Project ERROR: Unknown module(s) in qt: multimedia when building project with Qt Creator 6.0.2
body: <p>I am using a MacBook Pro if that helps.</p>
  <p>I'm trying to following through this course: <a href="https://web.stanford.edu/class/cs106x/index.html" rel="nofollow noreferrer">https://web.stanford.edu/class/cs106x/index.html</a></p>
  <p>And when I downloaded its first assignment and open it on Qt Creator, I saw the following error:</p>
  <p>Project ERROR: Unknown module(s) in qt: multimedia</p>
  <p>I have searched some related questions but didn't find a solution.
  And some information about my Qt Creator:</p>
  <p>Qt Creator 6.0.2</p>
  <p>Based on Qt 6.2.2 (Clang 12.0 (Apple), 64 bit)</p>
  <p>Can anyone help me out?</p>
