FFTW is a library for performing fast-Fourier transforms, and is
available from www.fftw.org. It is used by i.fft, i.zc, i.shape and
r.surf.fractal; if you don't need any of those programs, then you can
disable it with configure's "--without-fftw" switch.

Information regarding optional libraries can be obtained from the
REQUIREMENTS.html file, which resides in the top-level directory of
the GRASS source tree.
