New description:
If Cactus is built with MPI, enable the MPI bindings in FFTW3. Should one add MPI_LIBS to FFTW3_LIBS? HDF5 which can also optionally use MPI does so (added by me at one point). This is required for utilities I think that want to link against FFTW3 and which don't benefit from the thorn dependency tracking but can only use FFTW3_LIBS.

Comment:
Looks ok to me. Seems to work (from looking at this and my workstation and datura) for configurations using MKL for fftw3, debian and self-buiding.
