libkissfft-dev 131.1.0-3build2 (s390x binary) in ubuntu noble

 There are many great fft libraries already around. Kiss FFT is not trying to be
 better than any of them. It only attempts to be a reasonably efficient,
 moderately useful FFT that can use fixed or floating data types and can be
 incorporated into someone's C program in a few minutes with trivial licensing.
 .
 This package installs only files needed for development: header, libraries.
