[Debian-med-packaging] Bug#953855: libspdlog-dev: tries to include file that doesn't exist

[Hubert Chathi]

Package: libspdlog-dev
Severity: normal

Dear Maintainer,

As seen in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=952613,
nheko recently FTBFS after #include-ing /usr/include/spdlog/spdlog.h
which caused /usr/include/spdlog/fmt/fmt.h to be #includ-ed, which tried
to #include spdlog/fmt/bundled/core.h, which is no longer in
libspdlog-dev.  It looks like, since libspdlog-dev depends on
libfmt-dev, it should be #include-ing <fmt/core.h>, etc. instead of
trying to use the bundled version which doesn't exist.

I've worked around the FTBFS in nheko by defining SPDLOG_FMT_EXTERNAL
(and FMT_HEADER_ONLY) to force the use of the external libfmt.

Thanks
