CMake Error at CMakeLists.txt:6 (cmake_minimum_required):
  Compatibility with CMake &lt; 3.5 has been removed from CMake.

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

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3D3.5 to try configuring anyway.

The above is just how the build ends and not necessarily the most relevant pa=
rt.
If required, the full build log is available here (for the next 30 days):
https://debusine.debian.net/artifact/2412865/

The most likely cause of build failures is the removed backwards compatibilit=
y 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/155046/

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
