libnng-dev 1.7.2-1build2 (amd64 binary) in ubuntu noble

 Lightweight, broker-less library, offering a simple API to solve
 common recurring messaging problems, such as publish/subscribe,
 RPC-style request/reply, or service discovery. The API frees the
 programmer from worrying about details like connection management,
 retries, and other common considerations, so that they can focus on
 the application instead of the plumbing.

 This package contains the header files needed for developing programs
