How to install VidyoDesktop on Ubuntu 16.04 LTS?

I recently moved to Ubuntu 16.04 LTS and I noticed that VidyoDesktop was no longer available on my system. I tried to install it from the deb package using dpkg but I received the following error:

$ sudo dpkg -i VidyoDesktopInstaller-ubuntu64-TAG_VD_3_6_3_017.deb 
[...]
dpkg: problemi con le dipendenze impediscono la configurazione di vidyodesktop:
 vidyodesktop dipende da libqt4-gui (>= 4.8.1); comunque:
  libqt4-gui not installed.

I've noticed that libqt4-gui is not present in Ubuntu 16.04 repository. Does anyone know how to fix this? Thank you

Edit: My question is different from "How to install a deb file with dpkg". In fact I was asking how to install a specific package with a missing dependance.

The solution provided by Andrea works, but I'd like to report the exact command:

 sudo dpkg -i --ignore-depends=libqt4-gui VidyoDesktopInstaller-ubuntu64-TAG_VD_3_6_3_017.deb 

As the following link by Vidyo suggests,

https://support.vidyocloud.com/hc/en-us/articles/226103528-VidyoDesktop-3-6-3-for-Linux-and-Ubuntu-15-04-and-higher

one just needs to eliminate dependency on libqt4-gui (again, this case is already mentioned in previous answers but this is yet another approach.)

If I may, let me copy the solution from the above link and paste it here. I just made changes in the 3rd and 4th steps where I mention using vim editor instead of nano.

1) Download the VidyoDesktop .deb file to your home directory

2) Run the following commands from the terminal (replacing "vidyodesktop.deb" with the exact filename according to your system type)

$ cd ~
$ dpkg-deb -x vidyodesktop.deb vidyobuild
$ dpkg-deb --control vidyodesktop.deb vidyobuild/DEBIAN

3) Edit the package control file

$ vim vidyobuild/DEBIAN/control

Replace the entire Depends: line by copying and pasting the following:

Depends: libxss1,libaudio2,libasound2,libqt4-network

This removes the libqt4-gui transitional package dependency which is no longer required for recent Ubuntu versions

4) Save the customized .deb file

esc

:wq

enter

$ dpkg-deb -b vidyobuild vidyodesktop-custom.deb

5) Install the new VidyoDesktop .deb file by running

$ sudo dpkg -i vidyodesktop-custom.deb

[EDIT: Vidyo desktop works only in wifi mode. If the LAN cable is connected, then Vidyo shuts down. I haven't found a solution to this problem yet. But rest is working!]

My workaround has been to build a dummy libqt4-gui transitional package, using a control file based on the qt4-x11 source package and the equivs tools:

sudo apt install equivs
wget http://fwyzard.web.cern.ch/fwyzard/ubuntu/libqt4-gui/control
equivs-build control
sudo dpkg -i libqt4-gui_4.8.7_amd64.deb
sudo apt install -f
