    When this flag is enabled, an assertion will be generated during the
    execution of DEBUG configurations if you use a FIRFilter class to process
    FIRCoefficients with a size higher than 128, to tell you that's it would be
    more efficient to use the Convolution class instead. It is enabled by
    default, but you may want to disable it if you really want to process such
    a filter in the time domain.

    If this flag is set, then JUCE will use Intel's MKL for JUCE's FFT and
    convolution classes.

    If you're using the Projucer's Visual Studio exporter, you should also set
    the "Use MKL Library (oneAPI)" option in the exporter settings to
    "Sequential" or "Parallel". If you're not using the Visual Studio exporter,
    the folder containing the mkl_dfti.h header must be in your header search
    paths, and you must link against all the necessary MKL libraries.

    at runtime and use the library for JUCE's FFT and convolution classes.

    If the library is not found, then JUCE's fallback FFT routines will be used.

    This is especially useful on linux as fftw often comes pre-installed on
    popular linux distros.

    You must respect the FFTW license when enabling this option.

    for JUCE's FFT and convolution classes.

    You must add the fftw header/library folder to the extra header/library search
    paths of your JUCE project. You also need to add the fftw library itself
    to the extra libraries supplied to your JUCE project during linking.

    You must respect the FFTW license when enabling this option.

/** Config: JUCE_DSP_ENABLE_SNAP_TO_ZERO

    Enables code in the dsp module to avoid floating point denormals during the
    processing of some of the dsp module's filters.

    Enabling this will add a slight performance overhead to the DSP module's
    filters and algorithms. If your audio app already disables denormals altogether
    (for example, by using the ScopedNoDenormals class or the
    FloatVectorOperations::disableDenormalisedNumberSupport method), then you
    can safely disable this flag to shave off a few cpu cycles from the DSP module's
    filters and algorithms.
