[Rtk-users] RTK compilation

[Simon Rit]

Hi,
Great, thanks for the feedback. The FFTW stuff is probably a question for
the ITK forum but you can probably get around by using a pre-compiled
version of FFTW (I presume you're on windows). It's not mandatory for RTK
but improves the speed of filtering on the CPU.
