[Debian-med-packaging] Bug#952543: Using old libfmt breaks sopt and purify

[Ole Streicher]

Package: libspdlog-dev
Version: 1:1.5.0-1
Severity: serious
Affects: src:purify, src:sopt
Control: reassign 951995 libspdlog-dev
Control: reassign 951960 libspdlog-dev
Control: forcemerge -1 951995 951960

Since spdlog uses the old (included) libfmt, the builds of purify and
sopt fail with linker errors like:

undefined reference to `fmt::v6::internal::assert_fail(char const*, int,
char const*)

See the merged bugs for the reports. Could you revert this change? Or
somehow make it work (I guess, the library itself would need to be
included).

Thank you!

Best

Ole
