title: Qt project release ubuntu - error while loading shared libraries: libQt5Widgets.so.5
body: <p>I want to release my project written with Qt to a Ubuntu / Linux user. If they try to execute the build release version they get this error message, because they have not installed Qt:</p>
  
  <blockquote>
    <p>error while loading shared libraries: libQt5Widgets.so.5:
    cannot open shared object file: No such file or directory</p>
  </blockquote>
  
  <p>Is there a way to add all the libraries such as <code>libQt5Widgets.so.5</code> to the folder where the executable is, just like under Windows with <code>qt.conf</code>, where you can specify the <code>Plugins</code> folder?</p>
