You must install the libasound-dev package.
In theory you can compile Pd without ALSA altogether, but I don't think anyone ever does that, so it's bound to fail every now and again (in your case, you would also have to disable (local) portaudio)

There's nothing that needs to be fixing.
PipeWire has front-end for ALSA and JACK, so Pd can connect to PW right away (you probably need to install some glue package first, cannot check as I'm currently afk).
As a matter of fact, on my desktop machines I practically always run both Debian packaged Pd and self compiled Pds on PipeWire-enabled machines (not RPis though) without any problems.

IIRC, PipeWire actively discourages people from writing "native" support for it, and instead tells people to keep using whatever audio backends they already have.
