Merge ~chihchun/+git/mlt:debian-enabling-opencv into ~kdenlive/+git/mlt-old:debian

[Rex Tsai]

This change enabling opencv module, which allow the user to use motion tracker with kdenlive. Tested on 20.04 (focal).

[Rex Tsai (chihchun)]

It seems the opencv on 20.04 is too old, the plugin is available but the tracker is not actually working.

[Vincent Pinon (vpinon)]

Hello,
Thanks for your contribution!
Actually the tracker is in opencv_contrib, which is not built by most distributions.
We would need to rebuild opencv in the ppa, merging opencv_contrib into opencv source...
I don't know how to do that with dpkg?
