Accepting request 1043745 from home:alarrosa:branches:graphics
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): * 0001-Remove-LCMS-mutex.patch OBS-URL: https://build.opensuse.org/request/show/1043745 OBS-URL: https://build.opensuse.org/package/show/graphics/libjxl?expand=0&rev=11
