    #
    # Description
    #     Setup file for FFTW include/libraries.
    #     Sourced from OpenFOAM-<VERSION>/etc/cshrc
    #
    #     If using system-wide installations, use the following settings:
    #
    #         fftw_version=fftw-system
    #
    #     If the system fftw is unusable (eg, too old) and you don't
    #     have or want a ThirdParty installation:
    #
    #         fftw_version=fftw-none
    #
    #     If using a central installation, but not located under ThirdParty:
    #         - specify fftw-system
    #         - provide full paths for FFTW_ARCH_PATH
    #
    # Note
    #     When building OpenFOAM, any changes made here MUST be made in the
    #     equivalent config.sh version too, since that is the one which will
    #     be used during the build process.
