hint: Using 'master' as the name for the initial branch. This default branch
name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: git config --global init.defaultBranch <name>

hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.10 will be removed from a future version of
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.
CMake Error: CMake was unable to find a build program corresponding to "Ninja".
CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build
tool.

Update the VERSION argument <min> value. Or, use the <min>...<max> syntax

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/2410796/
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/154815/
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
