Since it is not an fmt bundled with spdlog, spdlog appears to be irrelevant.

Do not include headers from the same library in multiple locations.
That is your mistake.

#include "spdlog/fmt/bundled/format.h"
#include "fmt/ostream.h"

What if I need to use both spdlog and fmt/ostream.h?

[tt4g]

Use #include include/spdlog/fmt/ostr.h.
