Not a big problem now, but it could be a problem for Ubuntu 22.04 .

It seems that indeed libdc1394-22-dev was renamed to libdc1394-dev, see:

• https://packages.debian.org/search?keywords=libdc1394
• https://packages.ubuntu.com/search?keywords=libdc1394

Unfortunatly, while Ubuntu 20.04 and the last Debian stable (bullseye) have already libdc1394-dev and also a temporary libdc1394-22-dev package, Ubuntu 18.04 and Debian buster still only have libdc1394-22-dev, so we will need some conditional logic/documentation somewhere.

Note that the latest pc104 image is based on Debian Buster: https://icub-tech-iit.github.io/documentation/icub_operating_systems/pc104/icub-live/ , as Bullseye was just released a few weeks ago.

Unfortunatly, installing libdc1394-dev on Ubuntu 20.04 seems to uninstall some parts of opencv for some reason:

The following additional packages will be installed:
  libdc1394-25
The following packages will be REMOVED:
  libdc1394-22-dev libopencv-calib3d-dev libopencv-contrib-dev libopencv-dev libopencv-features2d-dev libopencv-highgui-dev libopencv-objdetect-dev
  libopencv-stitching-dev libopencv-videostab-dev
The following NEW packages will be installed:
  libdc1394-25 libdc1394-dev

So better to continue to use libdc1394-22-dev on all distros that we can.
