kimageformat-plugins should be built with HEIC / HEIF support

[Christoph Singer]

Description: Ubuntu 21.10
Release: 21.10
kimageformat-plugins:
  Installiert: 5.88.0-0ubuntu1~ubuntu21.10~ppa1

(but effects older versions, too)

Currently, kimageformat-plugins is built without support for HEIC / HEIC images. That's why Gwenview, Dolphin and other KDE apps can't show .heif images from modern smartphones like recent iPhones.

Enabling heif support is a matter of installing libheif-dev and rebuilding kimageformat-plugins with option KIMAGEFORMATS_HEIF=ON.

Please enable this by default. Thank you!

Status changed to 'Confirmed' because the bug affects multiple users.

This is even listed in the release note KDE Frameworks 5.80.0
https://kde.org/announcements/frameworks/5/5.80.0/#kimageformats

Please enable :)

I tested it on Ubuntu 22.04 alpha, libheif1 1.12.0-2build1, kimageformat-plugins 5.92.0-0ubuntu1.
The following additional files are installed:

dpkg -L kimageformat-plugins | grep heif
/usr/lib/x86_64-linux-gnu/qt5/plugins/imageformats/kimg_heif.so
/usr/share/kservices5/qimageioplugins/heif.desktop

I can contribute it but I don't see the ubuntu package git repo.

Also, in the meantime, here are the commands to manually rebuild & install the package with support: https://superuser.com/a/1713233/196387

Fixed in Kinetic with a sync from Debian
