    <p><code>Project ERROR: Unknown module(s) in QT: webkitwidgets</code></p>

  <p>I know that a lot of people already asked about this error, but most of the answers were to install <code>libqt5webkit5-dev</code> using this command line: <code>sudo apt-get install libqt5webkit5-dev</code>. </p>
  
  <p>The problem is, that I am on Windows, not on Linux, so this can't be useful for me.</p>
  
  <p><strong>The weird thing is</strong>, that I have <code>Qt5WebKitWidgets.dll</code> and <code>Qt5WebKit.dll</code> in <code>C:\Qt\Tools\QtCreator\bin</code>, so I suppose, that I have everything I need to use QWebView and to add this line <code>QT += webkitwidgets</code> without getting any errors.</p>
  
  <p>Also, I learned that WebKitWidgets is no longer supported after QT 5.0 and newer(or something like that), and I should use QtWebEngine, but I don't understand how to use it in Qt Widgets Application with QWebView. </p>
