The way to configure what FFT backends to use with VSIPL++, please
use the --enable-fft option. (The option accepts a comma-separated list
of backends.)
However, I'm not quite sure what you are trying to accomplish, as you
seem to want to disable FFT (you use "--with-fft=none"), yet you then
try to compile and run an FFT applet.

Typically, if no FFT backends are available, any code using vsip::Fft
objects will result in a compile-time error. (A way not to compile
any FFT backend in, yet prevent compile-time errors, is to use the
dummy "no_fft" backend, i.e., --enable-fft=no_fft.
