Hi,
During a rebuild of all packages in sid, your package failed to build
on arm64.
Relevant part (hopefully):

> ./build/CMakeFiles/CMakeTmp/./build/CMakeFiles/CMakeTmp/src.c:11: undefined reference to `pthread_create'

> /usr/bin/ld: ./build/CMakeFiles/CMakeTmp/./build/CMakeFiles/CMakeTmp/src.c:13: undefined reference to `pthread_cancel'

If you reassign this bug to another package, please marking it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects
If you fail to reproduce this, please provide a build log and diff it with me
so that we can identify if something relevant changed in the meantime.
About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
