[Qtwebengine] configure error on Ubuntu 15.04

[Ilia K]

Thanks again. I'm using https://wiki.qt.io/QtWebEngineHowToTry page but it
says nothing about QtWebChannel.

Is there any other dependencies/requirements for QtWebEngine? Can you send
me a step-by-step instruction how to build it on Linux?

P.S. QtWebChannel's build failed too:
