I have left "fmt" as an input to kodi since there is no longer a
conflict with "spdlog" (which has been reverted to version 1.13).
j4-dmenu-desktop depends on spdlog-1.15 which is incompatible with the
unversioned "fmt". It's no harm to duplicate a propagated input.

After rechecking that all dependent packages build (except the broken
rxcpp) I have pushed #77406 as
c53da8704b64e835d563b1b1ca64a44f0d1d9746 and #77964 as
0b83a27b67ae92e988795322ae988518ec3e6972.

Subject: spdlog is bundling fmt

Hello,

Today I tried to rebuild a package in my channel which uses both fmt and 
spdlog.

The build failed with a linking error with undefined references for some 
spdlog code.

Recently the spdlog symbol got updated to 1.15, when I downgrade to 
using spdlog 1.13 the error went away.

After looking around online for similar issues I found that the reason 
could be a version mismatch with the fmt package and the fmt bundled 
with spdlog.

If I use fmt-11 instead of fmt-9 (the fmt symbol) the issue went away.

I think Guix generally tries to unbundle things if possible and looking 
at some build recipes in other distributions (debian, gentoo, fedora) 
all of them add the -DSPDLOG_FMT_EXTERNAL=ON flag (usually with an 
additional patch to force the unbundled fmt)


Thanks.
