This is not true at all. The GPL on Linux does not impose any
requirements at all on software that runs on Linux, mostly because
they have an explicit exception on top of the GPL saying this. Using
FFTW means that if you distribute your software, you almost certainly
have to do it under the GPL or similar. This may or may not be a
problem (you might not distribute, you might be fine with the GPL,
etc.), but people should at least understand how licenses work.
