COMP: remove FindFFTW from ITK source tree so that we use the one from OTB/CMake dir

Utilities/ITK/CMake/FindFFTW.cmake

-## FFTW can be compiled and subsequently linked against
-## various data types.
-## There is a single set of include files, and then muttiple libraries,
-## One for each type.  I.e. libfftw.a-->double, libfftwf.a-->float
-
-## The following logic belongs in the individual package
-## MARK_AS_ADVANCED(USE_FFTWD)
-## OPTION(USE_FFTWD "Use double precision FFTW if found" ON)
-## MARK_AS_ADVANCED(USE_FFTWF)
-## OPTION(USE_FFTWF "Use single precision FFTW if found" ON)
