I am trying to install gromacs 4.6-beta2 on a high performance cluster. I
get stuck in the cmake configuration stage with an error from
FindFFTW.cmake, with the following error:

bash-4.1$ CMAKE_PREFIX_PATH=/usr/local cmake ../gromacs-4.6-beta2
-- Enabling native GPU acceleration
CMake Warning at cmake/gmxManageMPI.cmake:100 (MESSAGE):

  at the error message in
  to find out what went wrong.  If you are using a static lib (.a) make sure
  you have specified all dependencies of fftw3f in FFTWF_LIBRARY by hand
  (e.g.  -DFFTWF_LIBRARY='/path/to/libfftw3f.so;/path/to/libm.so') !

Actually, the fftw library on the cluster works fine and I verified that it
contains the fftwf_plan_r2r_1d function. I tried to use the -DFFTWF_LIBRARY
flag with no effect. I use cmake version 2.8.9.  Any ideas?

Thanks in advance!
