Unable to get away the error though I added QtWebkit(5.5.1) sources along
with Qt 5.6.3 sources and use below configure line:

./configure -prefix /home/ubuntu/qt5 -opensource -confirm-license
-qt-libjpeg -qt-zlib -qt-libpng -sql-sqlite -no-cups -no-opengl
-no-qml-debug -skip qt3d -skip qtactiveqt -skip qtandroidextras -skip
qtcanvas3d -skip qtconnectivity -skip qtdeclarative -skip qtenginio -skip
qtgraphicaleffects -skip qtlocation -skip qtmacextras -skip qtmultimedia
-skip qtquickcontrols -skip qtquickcontrols2 -skip qtscript -skip qtsensors
-skip qtserialbus -skip qtserialport -skip qtwayland -skip qtwebsockets
-skip qtwinextras -skip qtx11extras -skip qtxmlpatterns -nomake tools
-nomake tests -nomake examples -no-use-gold-linker -no-iconv -no-pulseaudio
-no-alsa -no-mtdev -dbus -fontconfig -no-libudev -no-openssl -qt-pcre -v

I installed needed dependencies of Qt Webengine,QtWebkit and libxcb as
mentioned in https://wiki.qt.io/Building_Qt_5_from_Git

The older versions of Qt had been installed in /home/ubuntu/ different
Though I remove the older versions of installed Qt, it still throws the
qt_version_tag error.

Do I need to modify any QtWebkit sources/configuration to link against the
Qt 5.6+?
