To add Capturefab to your application launcher, install capturefab on your PATH,
then copy the contents of share/ into ~/.local/share/ (or /usr/local/share/
for all users). Keep the applications/ and icons/ subdirectories intact.

USB3 Vision cameras: copying share/ into ~/.local/share does not install the
udev rule that lets you open them. Install it once, then replug the camera:
  sudo install -m 644 share/udev/rules.d/70-capturefab-usb3vision.rules /etc/udev/rules.d/ && sudo udevadm control --reload && sudo udevadm trigger --subsystem-match=usb --action=add
