> Do you guys remember how [adding it](https://github.com/Slicer/Slicer/commit/2a99657052a2cad890f7d1a754ba2ae76496aa76) broke the Windows packaging?

It led to the following on Windows:

> [@Latest nightly build won´t work](https://discourse.slicer.org/t/latest-nightly-build-won-t-work/11827/1):
>
> I kept receiving messages saying a series of dll files were missing (Qt5Core, Qt5Gui, Qt5Network, Qt5WebChannel, Qt5WebEngineWidgets, Qt5Widgets and Qt5Xml).

and on Linux:

> [@Error executing version Slicer-4.11.0-2020-06-01-linux-amd64.tar.gz on Ubuntu 16.04](https://discourse.slicer.org/t/error-executing-version-slicer-4-11-0-2020-06-01-linux-amd64-tar-gz-on-ubuntu-16-04/11834/1):
>
> qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.  
> This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
