How to build OpenCV 4 debian .deb packages properly?

1

I use ROS Noetic built from source on Raspberry PI 4 armhf debian buster platform.
When I install ROS dependencies - it installs OpenCV debian packages libopencv-* , available on Index of /debian ,
which are compiled OpenCV version 3.2.0
(for example - Debian -- Details of package libopencv-calib3d3.2 in buster , etc)
But I need to run newer OpenCV version, 4.1, or latest 4.5
I’d like to build my own .deb repository with 4th OpenCV version - and take packages from it as I install ROS, not from Index of /debian

I have tried this script
It has downloaded source code from opencv github, and compiled me the following files:
OpenCV-4.1.0-armv7l-dev.deb
OpenCV-4.1.0-armv7l-libs.deb
OpenCV-4.1.0-armv7l-licenses.deb
OpenCV-4.1.0-armv7l-main.deb
OpenCV-4.1.0-armv7l-python.deb
OpenCV-4.1.0-armv7l-scripts.deb

But this packages are not sutable to resolve ROS dependencies - I need to have .deb names like libopencv-calib3d4.1 , etc.

I tried to clone this repository instead of GitHub - opencv/opencv: Open Source Computer Vision Library
But it fails to cmake the source folder:

-- Configuring incomplete, errors occurred!

Hello! Also interested in how to do it. Did you manage to figure it out?

No, we did not. I use ROS repos precompiled.

Thanks @ipetrov for pointing the Debian Science Team OpenCV repo. @standmit just FYI, this is how I managed to build all the .deb installers in an Ubuntu Focal Dockerfile (x86_64).
