[NFBCS] IPEVO Visualizer & Ubuntu Linux 23.10

[Mike Gorse]

I don't really have an answer for you, but your version of Ubuntu likely 
ships a newer version of opencv than the one that your package is 
expecting. I don't use Ubuntu or Debian, but I'm guessing apt has an 
option to force the installation of a package. Running it with the newer 
version of opencv might work, or it might not. Otherwise you might need to 
build an older version from source.

It's really the sort of problem that tools like flatpak were designed to 
solve, but that doesn't help you right now.
