just a data-point: on Debian/ppc64el juceaide builds fine, at least for JUCE-7.0.1

https://buildd.debian.org/status/fetch.php?pkg=juce&arch=ppc64el&ver=7.0.1%7Eds0-1&stamp=1659651853

EDIT: on closer inspection I see that your error is about undefined symbols related to png. For the Debian package, we take care to properly link against the system's libpng, so that might explain why it works for us.
