Expected behaviour

For it to install quickly.

Actual behaviour

If you run pip3 install opencv-python the installation appears to get stuck at Building wheel for opencv-python. I left it for about an hour with no visible progress.
I've since run pip3 install opencv-python --verbose and as of writing I'm an hour in at 28%.

Steps to reproduce

• See above
• Raspberry Pi OS Bullseye
• ARM
• 4.8.1.78

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python
