Expected behaviour

use the latest libpng 1.6.37

Actual behaviour

image
libpng15 in use

image
opencv use 1.6.37

Steps to reproduce

  • example code
  • operating system
  • linux x86
  • opencv-python version 4.5.2.54
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

                Steps to reproduce
                • example code
                • operating system
                • linux x86
                • opencv-python version 4.5.2.54
                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
