requested to merge pobrn/wireplumber:set_WIREPLUMBER_CONFIG_DIR_instead into next
This is needed for wireplumber to start up correctly in the meson
devenv when built as a subproject of pipewire. The reason for this
is that the value set for `PIPEWIRE_CONFIG_DIR` in the wireplumber
meson build file will be overriden when the pipewire meson files
set up another devenv with its own `PIPEWIRE_CONFIG_DIR`.
An alternative solution is to make pipewire support multiple directories in
PIPEWIRE_CONFIG_DIR and use
env.prepend() when setting
PIPEWIRE_CONFIG_DIR in the pipewire devenv.
I am not sure which one is better. Is
WIREPLUMBER_CONFIG_DIR deprecated? Is its use discouraged?
