Would you consider adding "-DFEATURE_relocatable=OFF" to the cmake
parameters for this package? This was previously added for debian's Qt5
build. While I can't demonstrated a problem on sid, there is a problem
on Ubuntu jammy
https://bugs.launchpad.net/ubuntu/+source/qt6-base/+bug/1970057. The
problem shows up on systems that have links in the dynamic loader search
path like jammy. There is a patch available:
https://bugs.launchpad.net/ubuntu/+source/qt6-base/+bug/1970057/+attachment/5585995/+files/2-qt6-base_6.2.4+dfsg-2ubuntu2.debdiff
Here is the debian changelog entry from Qt5:
qtbase-opensource-src (5.14.2+dfsg-3) unstable; urgency=medium
* Build with -no-feature-relocatable, to fix paths on usr-merged systems
(closes: #961554).
If there is something else I can do to help fix this please let me know.
Thanks,
Steve
