Regarding this error:
error: "FFTW 3.3.2 or later is required so that FFTW_WISDOM_ONLY is
defined."
Did you try FFTW 3.3.3 ?
http://www.fftw.org/download.html
Did I miss something(sorry, I didn't go through the entire stream)
P.S.
When you build your own project and using ITK as an external library, as
long as you set up "ITK_DIR" correctly,
the corresponding ${ITK_DIR}/ ITKConfig.cmake will be used.
