The WEBRTC_HAS_NEON macro that enables using NEON implementations is unconditionally set for arm64 and the 'neon' build option is ignored, assuming we always want to use the NEON-specific implementations instead of generic ones. This is an OK assumption to make because arm64 CPUs always support NEON. But the code handling the build option ended up quite convoluted. As part of cleaning up, set the relevant cflags after we handle the build option. This also means that we can make 'runtime' fall back to 'no', and disable NEON-specific code with -Dneon=no.

About
This is meant to be a more Linux packaging friendly copy of the AudioProcessing module from the WebRTC project. The ideal case is that we make no changes to the code to make tracking upstream code easy.
This package currently only includes the AudioProcessing bits, but I am very open to collaborating with other projects that wish to distribute other bits of the code and hopefully eventually have a single point of packaging all the WebRTC code to help people reuse the code and avoid keeping private copies in several different projects.
Building
This project uses the Meson build system. The quickest way to build is:
# Initialise into the build/ directory, for a prefixed install into the
# install/ directory
meson . build -Dprefix=$PWD/install
# Run the actual build
ninja -C build
# Install locally
ninja -C build install
# The libraries, headers, and pkg-config files are now in the install/
# directory
Feedback
Patches, suggestions welcome. You can file an issue on our Gitlab repository.
Notes
- It might be nice to try LTO on the library. We build a lot of code as part of the main AudioProcessing module deps, and it's possible that this could provide significant space savings.
