The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here (for the next 30 days):
https://debusine.debian.net/artifact/2402405/
The most likely cause of build failures is the removed backwards compatibility
for
CMake versions earlier than 3.5. You can find additional information in my
debian-devel announcement:
https://lists.debian.org/debian-devel/2025/04/msg00310.html
About the archive rebuild: The build was made on debusine.debian.net,
using sbuild.
You can find the build task here:
https://debusine.debian.net/work-request/153889/
If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.
Thanks,
Timo
