Trying to compile niri 26.04 on debian stable (bookworm at the time of writing).
Compilation fails because it's missing a symbol from libpipewire. Please see similar issue and the fix in SDL (it's explained in the commit comment): libsdl-org/SDL@1d0ecf9:

pipewire: Don't require pw_check_library_version() with Pipewire < 0.3.75
The Debian 12 'bookworm' stable release only has 0.3.65, which is earlier
than the introduction of that symbol. Similarly, Steam Runtime 3 'sniper'
and Steam Runtime 2 'soldier' have a backport of 0.3.65 from Debian 12,
so they have the same limitation.
