title: QtWebEngine - procedure not found
body: <p>I have a simple C++ (non Qt Quick) application (that does not use .pro mechanism) built against the official Qt 5.4.2 x64 build (with openGL support).
  As soon as I use the QWebEngineView object in my application, it fails to load with a message "Specified procedure could not be found".</p>
  
  <p>With the help of gflags, it seems it fails to find the following demangled procedure: </p>
  
  <pre><code>public: __cdecl QOpenGLWidget::QOpenGLWidget(class QWidget * __ptr64,class QFlags&lt;enum Qt::WindowType&gt;) __ptr64
  </code></pre>
  
  <p>I am not sure to understand why this cannot be found, I have put for the sake of testing all the dlls in Qt_DIR\bin next to the application, and all the plug-ins.
  The preprocessor list I use to build my app are as follow:</p>
  
  <pre><code>WIN32;_DEBUG;_WINDOWS;_USRDLL;WIN64;QT_WEBENGINEWIDGETS_LIB;QT_WEBENGINE_LIB;QT_QUICK_LIB;QT_PRINTSUPPORT_LIB;QT_WIDGETS_LIB;QT_GUI_LIB;QT_QML_LIB;QT_NETWORK_LIB;QT_UITOOLS_LIB;QT_CORE_LIB;WIN32PROJECT5_EXPORTS;PLUGIN_VENDOR_NAME="$(VendorName)";PLUGIN_VERSION="$(PluginVersion)";PLUGIN_NAME="$(PluginName)";%(PreprocessorDefinitions)
  </code></pre>
  
  <p>And the input libraries:</p>
  
  <pre><code>Qt5Cored.lib;Qt5Guid.lib;Qt5Widgetsd.lib;Qt5WebKitd.lib;Qt5WebKitWidgetsd.lib;Qt5WebEngineWidgetsd.lib;Qt5WebEngined.lib;Qt5OpenGLExtensionsd.lib;Qt5OpenGLd.lib;Qt5Networkd.lib;Qt5Xmld.lib;D:\NotBackedUp\Tools\Qt\5.4\msvc2013_64_opengl\lib\qtmaind.lib;shell32.lib;Qt5Quickd.lib;Qt5PrintSupportd.lib;Qt5Qmld.lib;Qt5UiToolsd.lib;glu32.lib;opengl32.lib;gdi32.lib;user32.lib;o2d.lib;%(AdditionalDependencies)
  </code></pre>
  
  <p>I wanted to try a simple example in Qt Creator 3.6.1 but it complains: Project ERROR: Unknown module(s) in QT: webenginewidgets</p>
  
  <p>The browser.exe example runs fine (built with visual studio)</p>
  
  <p>Do you have any idea of what is wrong?
  PS: I am on windows 8.1.</p>
