Latest opencv (4.7.0.68) introduces fatal backward compatibility issue with ZLIB.

System Information

OpenCV python version: 4.7.0.68
Operating System / Platform: quay.io/pypa/manylinux_2_24_x86_64
Python version: 3.8+
ZLIB version: 1.2.8

OpenCV python version: 4.7.0.68
Operating System / Platform: quay.io/pypa/manylinux2014
Python version: 3.8+
ZLIB version: 1.2.7

Detailed description

The latest opencv (4.7.0.68) requires ZLIB >= 1.2.9. This upgrade introduces fatal backward compatibility issue, since the dominant platforms like manylinux2014 and manylinux_2_24_x86_64 can't meet the requirement, especially the related wheels are shipped with platform tag manylinux2014_x86_64. As a consequence, running the latest opencv (4.7.0.68) on those platforms raises the version ZLIB_1.2.9 not found error.

Steps to reproduce

docker run --rm -it quay.io/pypa/manylinux2014_x86_64

/opt/python/cp38-cp38/bin/pip install opencv-python-headless
/opt/python/cp38-cp38/bin/python -c 'import cv2 as cv'

docker run --rm -it quay.io/pypa/manylinux_2_24_x86_64

/opt/python/cp38-cp38/bin/pip install opencv-python-headless
/opt/python/cp38-cp38/bin/python -c 'import cv2 as cv'

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)

I see the same exception in aws lambda workload
[ERROR] Runtime.ImportModuleError: Unable to import module 'app': /lib64/libz.so.1: version `ZLIB_1.2.9' not found (required by /var/task/cv2/../opencv_python.libs/libpng16-186fce2e.so.16.37.0)
Traceback (most recent call last):

I reverted back opencv_python version to 4.6.0.66 in requirement.txt after the change no issues noticed.

Same issue on CentOS 7.9.2009.

[dzienki]

What comand or library install ZLIB?
