title: How to compile with Qt Creator
body: <p>I'm trying to compile this source with Qt Creator: <a href="https://github.com/Oen44/QPropertyEditor" rel="nofollow noreferrer">QPropertyEditor</a></p>
  <p>What I do is just clone the repo, double click the .pro file:</p>
  <p><a href="https://i.stack.imgur.com/0Inum.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0Inum.png" alt="enter image description here" /></a></p>
  <p>Then I right click in the project, and build:</p>

  <p>I'm getting this errors:</p>
  <p><a href="https://i.stack.imgur.com/4tuyl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4tuyl.png" alt="enter image description here" /></a></p>
  <p>I've checked the output directory and I guess it's correct: <code>%{Config:DefaultProjectDirectory}</code></p>
  <p>I don't know what to do now, I only used Visual Studio, it's my first time with Qt and I can't find anywhere the option to build debug files, etc</p>
