I tested this in a Leap 15.4 system with kimageformats 5.100.0
and gwenview5 and it could open/save jxl files correctly.
The test was built in
home:alarrosa:branches:openSUSE:Backports:SLE-15-SP4:kimageformats
With this, we can submit jxl support to Backports for SLE15-SP5/
Leap 15.5
- Add patch (applied reversed) to revert the requirement for an
updated liblcms2 library when we have an older one. This allows
libjxl to build in SLE15 SP4/SP5 (and Leap 15.4/15.5):
