Hello, I see dh-cmake FTBFS in Ubuntu due to this:
An update from the python-debian side - in git, all the packages that
were in Recommends were moved to Suggests. Libraries recommending
packages has always been something I thought was odd - a library is
always being driven by some calling code that knows whether it needs
certain features and so it needs to take responsibility for ensuring
that optional dependencies are present.
In the case of dh-cmake, it feels to me like dh-cmake knows that it is
going to manipulate .deb files and for that, the optional dependencies
to do so should be installed too (zstd). In the same way something that
knows it wants to check gpg signatures on Release files should ask for
gpgv to be installed so that the deb822 module can oblige.
Asking dpkg to do the decompression rather than zstd would also be
plausible (based on dpkg-deb --fsys-tarfile and --ctrl-tarfile).
However, I think that would be a substantial rewrite of the way the
DebPart class is built and, for the purposes of portability, we'd want
the pure python methods to still work (except Ubuntu deb files). I'd be
happy to see a patch that tried but I suspect it would be too invasive
for bookworm at this stage.
It's hard to see a way of avoiding a delta somewhere between Debian and
Ubuntu, either by having dh-cmake or python3-debian drag in zstd. My
suggestion is that it should be with dh-cmake since that is what needs
zstd, not all the myriad other uses of python3-debian.
