Hi! and thanks for the early warning.
It looks like doxygen 1.15.0 actually bundles fmtlib 11.2.0:
https://github.com/doxygen/doxygen/blob/master/deps/fmt/README.md
which we'll unbundle and override with our own packaged version.
Therefore it's certainly compatible.
I tried with your version from experimental and it currently fails with:

but that's because also libspdlog-dev needs to re be rebuilt with libfmt 11.
This will autoclose when I upload doxygen 1.15.0+ds1-1.
