Dear maintainer,

your package has an autopkgtest regression with CMake 4, caused by 
the removal of deprecated backwards compatibility settings.

You can find more information in my debian-devel announcement: 
https://lists.debian.org/debian-devel/2025/04/msg00310.html


Hopefully relevant excerpt from 
https://ci.debian.net/packages/f/ffc/unstable/amd64/64721193/ follows:


233s CMake Error at CMakeLists.txt:43 (cmake_minimum_required):
233s   Compatibility with CMake < 3.5 has been removed from CMake.
233s
233s   Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
233s   to tell CMake that the project requires at least <min> but has been updated
233s   to work with policies introduced by <max> or earlier.
233s
233s   Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.
