opencv vs opencv2

[kanaida2]

I'm using manjaro, and howdy.
howdy relies on opencv (4.5.2-2)

butterflow relies on a package called opencv2 (2.4.13.6-1) which causes a conflict. It wants to remove my newer version...
So howdy won't work for facial recognition login after that...

can you please update your program to use opencv?

I think opencv (1) is old. It's probably the case that, if anything, opencv3 would be the next appropriate upgrade.
