CMake Error at CMakeLists.txt:15 (CMAKE_MINIMUM_REQUIRED):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

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/2402762/

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/153928/

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
