During the ./configure of gromacs on my Cygwin Bash Shell, I get the following error:

configure: error: Cannot find fftw3f library

I have installed fftw3, but evidently not to the satisfaction of gromacs. I put the fftw3.h in usr/local/include, and that enabled me to make it past the fftw3.h. I put the libfftw3*.dll's in user/local/lib, but maybe that's not where they go. The fftw site acts like there is nothing special to installing fftw (just download and unzip).

Any help would be appreciated.

Gromacs needs floating-precision version of fftw3 while fftw3 defaults to double-precision. Re-build fftw3 with support for single-precision.
