#
# Description
#     Setup file for FFTW include/libraries.
#     Sourced from OpenFOAM-<VERSION>/etc/bashrc
#
#     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 _foamAddLib is unset (eg, called from makeFFTW):
#         - fftw_version variable is retained.
#         - the LD_LIBRARY_PATH is not adjusted.
