[gmx-users] question about fftw3 in gromacs 4.6 installation

[Albert]

Hello:

  I am compiling the latest gromacs 4.6 with command:

cmake .. -DGMX_MPI=ON -DCMAKE_CXX_COMPILER=/soft/openmpi-1.4.3/bin/mpiCC 
-DCMAKE_C_COMPILER=//soft/openmpi-1.4.3/bin/mpicc 
-DCMAKE_INSTALL_PREFIX=/soft/gromacs4.6 -DGMX_GPU=OFF 
-DBUILD_SHARED_LIBS=OFF -DFFTW_INCLUDE_DIR=/soft/fftw-3.3.3/include

and I get get the following messages. It seems that it doesn't take my 
own compiled FFTW  but it used the system FFTW:

   Manually-specified variables were not used by the project:

What's more, I compiled fftw3 with options:
./configure --enable-sse --enable-float --with-pic 
--prefix=/soft/fftw-3.3.3 --enable-single --enable-static --enable-mpi

And I don't find libfftw3f.so in my installation directory:

ls /soft/fftw-3.3.3/lib
libfftw3f.a  libfftw3f.la  libfftw3f_mpi.a  libfftw3f_mpi.la pkgconfig

thank you very much
best
