CMake Error at CMakeLists.txt:1 (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/2392029/ 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/152832/ 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

I have downgraded the bug to non-RC severity temporarily and reverted
CMake in unstable to version 3.31.6. I plan to re-upgrade in about a
month's time. I realize that despite my April announcement, the upload
to unstable came rather surprising, and I don't want to cause
unnecessary pain.

Also, the build log URL has an unfortunate mistake. The correct URL
should include the workspace, i.e.,

https://debusine.debian.net/debian/developers/artifact/XXXX

CMake 4 will also be available in experimental again, so it can be
used to verify that the bug is fixed.

Cheers
Timo
