    Build options: Use FFTW instead of the bundled KissFFT
    
    The libfftw3 dependency is no longer sufficient to implicitly enable it!
    This behavior has changed from version 1.9.0 to 1.9.1.
    
    libsamplerate was already used implicitly but enabling it explicitly
    will avoid that it is silently ignored after a future update.
