Hi Vladimir,

that happens because spdlog has been build against fmt >= 10.x: I found
this patch in the archlinux repo that let coeurl build also in this
situation

https://nheko.im/nheko-reborn/coeurl/-/commit/831e2ee8e9cf08ea1ee9736cde8370f9d0312abc.patch

Matteo

P.S. please use sane email addresses when you write to the mailing list,
thanks in advance! ;-)
