libraries, when available, or you can link to a precompiled FFTW

library. Please note that you must use FFTW version 2. Support for
|

version 3 is in progress: contact the developers if you want to try.

At compilation time you have to choose whether to use the built-in

copy of FFTW (v.<3), a precompiled FFTW v.<3 library, or a
|

precompiled FFTW v.3 library. This is done using preprocessing

options with rather obvious meaning : __FFTW, __USE_INTERNAL_FFTW, __FFTW3

IBM, if available (only on AIX).
