[Debian-med-packaging] Bug#1087736: libspdlog-dev should not depend on catch2

[Nicolas Peugnet]

Package: libspdlog-dev
Version: 1:1.12.0+ds-2+b3
Severity: normal

Dear Maintainer,

While trying to build a new version of j4-dmenu-desktop (that I am
currently updating) with the 'nocheck' build profile, I noticed that
catch2 was still installed, as a dependency of libspdlog-dev, which
in turn, seems to be the reason why j4-dmenu-desktop is not
crossbuild-able anymore [1].

I made a quick grep in the spdlog sources and did not find any
references to catch2 outside of the tests directory. So I don't
understand why should catch2 be a dependency of libspdlog-dev.

Could you please remove this dependency, or if it is really needed,
explain why it is the case?
