This change also puts the `target/` directory first, for locally-built
plugins to take priority over distribution-provided plugins. It also
encloses the environment variable in quotes, in case it contains paths with
spaces.
cargo-c will produce a pkg-config file making it easier to statically
link plugins.
Also add 'static' features for plugins depending on < 1.14 as this is the
minimal required version to use static linking because of ABI changes in
core.
The audiornnoise element can be used as playbin audio-filter for instance, to
suppress noise in the audio stream.
This plugin relies on the nnnoiseless crate which implements the noise removal
algorithm of the Xiph RNNoise library, in Rust. Some demos and documentation of
the RNNoise C library can be found on:
