Fix Qt app packaging.
What does this MR do?
Closes #244 (closed)
Installed and packaged apps looked bad because we forgot to ship the qt styles
plugin.
How to test it?
- Build an app (Use the cmake
PROJECTS_TO_BUILD
variable to set an app e.g. OgreViewer ARCalibration VRRender) - Install and package it (
ninja install && ninja package
) - Install the packaged app, it shouldn't look like a windows 95 app.
