[Insight-users] how to use FFTW with ITK

[Jakub Bican]

Hello,

you should turn ON the two options

   USE_FFTWD
   USE_FFTWF

when configuring ITK. It asks you for the FFTW libraries and include path.

After compilation, ITK will be FFTW-enabled.

You do not need to mention FFTW in your CMakeLists.txt file.

Regards,

   Jakub
