Unable to disable webrtc dependency
As a maintainer for the pipewire package, I wanted to create i686 and x86_64 packages from the same source, but failed since webrtc lib was found for 64-bit but unable to disable for 32-bit. (Meson Option if 'echo-cancel-webrtc').
I noticed this is due some code in spa/plugins/aec/meson.build.
The attached patchmake-webrtc-optional.patch fixes this for me.
