Installing FFT3Dfilter

I want to give FFT3Dfilter a try. I've looked at documentation but it's unclear what's supposed to be done with the various files that get unzipped.

Files from the zip file for version 2.1.1 I've struck out the files that I recognize.

Per this page http://avisynth.org.ru/fft3dfilter/fft3dfilter.html which is also bundled with the zip file you're supposed to install fast external FFTW library version 3


Files from fftw3win32mingw
