I don't have access to Cygwin so I can't test this. The attached patch
should disable compilation of sander.RISM.MPI and RISM into MPI NAB
(even if it has been requested) on cygwin. I have done some limited
testing and it does seem to work.

Is any of the distributed code using FFTW 3? It seems to only be used
by MDGX and there is currently no option to turn MDGX on.
