Historically, I believe libheif was only in the RPMFusion repos because it originally only supported HEIF (patent-encumbered) images. However, now that it supports AVIF (free format), libheif exists in the main Fedora repos.

Would it be possible to enable kimageformats' support for that library? In my local testing, adding libheif-devel as a build dependency and passing in the -DKIMAGEFORMATS_HEIF=ON CMake option seems to do the trick.

Thanks!

Reproducible: Always
