QtWebEngine qmake error: unkown module: webchannel

I am trying to get qt webengine running on my laptop for the first time, but can't seem to build it. I am following the instructions from here:
On the last few steps, I had to run "qmake -r" on the qtwebengine directory. This is the output:
SSL............................... Using system NSS
ICU............................... Using internal copy (Default, force system ICU with WEBENGINE_CONFIG += use_system_icu)
FFMPEG............................ Using internal copy (Default, force system FFMPEG with WEBENGINE_CONFIG += use_system_ffmpeg)
Proprietary codecs (H264, MP3).... Not enabled (Default, enable with WEBENGINE_CONFIG += use_proprietary_codecs)
Project ERROR: Unknown module(s) in QT: webchannel
This error happened right after I installed WebKitGtk+ from here (http://trac.webkit.org/wiki/BuildingGtk) and ran "Tools/gtk/install-dependencies" and "Tools/Scripts/update-webkitgtk-libs". Before I installed WebKitGtk+, qmake would terminate at a later point.
(I installed WebKitGtk+ because, previously, running "qmake -r" on the qtwebengine directly resulted in an "unmet dependency: harfbuzz" error that I tried to fix on my own via google, and the WebKitGtk+ page was the only lead I could find that would supposedly fix that issue... big mistake!).
I am running on a (mostly freshly reformatted) Ubuntu 15.04 laptop. I installed qt5 via apt-get install, but apparently I have both qt4 and qt5 plugins installed, as well as qtchooser (I'm guessing from the WebKitGtk+ installation scripts).
Here is the output of "qmake --version":
QMake version 3.0
Using Qt version 5.4.1 in /usr/lib/x86_64-linux-gnu
I've spent the past 3days or so trying to fix this error, but have no idea what to do next. Any help would be greatly appreciated, as I'm excited to try out qt webengine!
Hi and welcome to devnet,
Looks like your missing the QtWebchannel module

Thanks SGaist. I did a little more investigating, and it turns out downloading qt 5.5.0 from http://download.qt.io/official_releases/qt/ fixed all the build issues. I'm not sure how to mark this as solved, is a mod suppose to do that for me?
You're welcome !
No, you can do it yourself using the "Topic Tool" button :)
