[hpsdr] Non-GPL FFT libraries?

[Jeremy McDermond]

The Mac and iOS both ship with FFT implementations built into the operating system.  It's part of a framework called "Accelerate" and is written by Apple's supercomputing group.

See http://www.apple.com/acg/  https://developer.apple.com/performance/accelerateframework.html and http://www.macresearch.org/performance_tutorial_part_i_introducing_accelerate.

I know that some people here have been working on non-GPL software (yes, I'm bringing up the Apple Store again) so I'm curious as to what other libraries people have used and how they might compare to each other.
