Use of variables like %{buildDir} in QtCreator kit settings in Qt5 : <p>In <a href="http://doc.qt.io/qtcreator/creator-run-settings.html" rel="noreferrer">this documentation</a> (under section "Specifying a Custom Executable to Run") I noticed that there is mention of what looks like a variable <code>%{buildDir}</code> in the field "Working directory".</p>

<p>I have struggled for a while now to find documentation for this feature. I would like to know first of all <strong>is there documentation for this somewhere?</strong>.</p>

<p>Secondary questions: </p>

<ul>
<li>What other variables are available?</li>
<li>In which fields can they be used?</li>
<li>Can I access variables that I created in my project's <code>.pro</code> file?</li>
<li>Are there any other eval features or is this mechanism limited to  variables?</li>
</ul>

<p>Thanks!</p>
