title: Avoid attaching debugger in Qt5 QTest
body: <p>I have a small <code>QTest</code> case that crashes. Even if I run this as a normal program (no debugger) it seems that <strong>GDB</strong> is attached by qmake/QtCreator/<em>something</em> when it finds that the program crashed.</p>
  
  <p>However, I would like to run my QTest without this happening. How can I configure my project to avoid the debugger being invoked for normal non-debugging sessions?</p>
  
  <p>To demonstrate what I mean, please have a look at the following test output when running my test without debugger(I just press the big green play button without a bug on it in QtCreator):</p>
