The face localization option is off

[adrianmay]

When I start eviacam I get the above message and then it crashes.
I have two cameras. It once asked me which to use before dying from opencv deprecating the main open-cam api, so I rebuilt against opencv 4.0.1, but it hasn't asked again which cam to use.
I don't have any files in ~/.eviacam
Arch linux.
Built at d5db860 against gtk 3.24.13, wxWidgets 3.1.3 for gtk3 and opencv 4.0.1

The message is because eViacam is not able to find the haarcascade_frontalface_default.xml that comes with opencv. In visionpipeline.cpp:80-105 the searched paths are listed.
