libvips package doesn't install libpng; Installing libpng doesn't enable vips to process png files

[AlvesJorge]

Hello 👋

Steps to reproduce:

• run docker run --rm -it --user root --entrypoint=/bin/sh cgr.dev/*.com/ruby:3.3.6-dev
• run apk add libvips-dev
• run apk add libpng
• run vips --vips-config
• Confirm this line PNG load/save with libspng or libpng: false

I have not found any information about this anywhere, so any input is apprecciated

@AlvesJorge This should fix it #37075

related #37054

Thank you for the fast reply @tuananh
I'm curious, what specifically in that PR would enable the png features?

-Dauto_features=enabled this one would bring in all the auto features, minus a few that I disable because we dont have it packaged in Wolfi (those with -Dxxx=disabled)

List of auto features can be found here https://github.com/libvips/libvips/blob/master/meson_options.txt

Oh ok thank you, do you know if this is something I can enable when installing the package? As a temporary fix while your PR is not merged :)

[tuananh]

I dont know. What we did at work is we setup a private repo for this kind of situation. If you have it already, you can do that. Otherwise, probably need to wait.

It's holidays so I guess it will be awhile

Thank you for your time :) Happy holidays :)
