[gmx-users] compiling GPU 4.5b2, CUDA_INCLUDE_DIRECTORIES function is undefined

[chris.neale at utoronto.ca]

Dear users:

I previously posted about difficulties compiling gromacs 4.5b2 for GPUs:
http://lists.gromacs.org/pipermail/gmx-users/2010-August/052905.html

It turns out that this problem was not directly related to version.

First, I had to add -DLIB_INSTALL_DIR=$(pwd)/install_dir to the cmake call.

Second, (and it is here that I am stuck), the error message:

CMake Error at kernel/gmx_gpu_utils/CMakeLists.txt:18  
(CUDA_INCLUDE_DIRECTORIES):
   Unknown CMake command "CUDA_INCLUDE_DIRECTORIES".

is telling me that the function CUDA_INCLUDE_DIRECTORIES is undefined.  
Indeed, I can't find reference to it in any other files.

Just to be sure, I downgraded to cmake v2.6.4, but I get the same  
error. Here is my full command line and my error message:

export  
OPENMM_ROOT_DIR=/project/pomes/cneale/GPC/exe/OpenMM2.0-Source/exec/openmm
/project/pomes/cneale/GPC/exe/cmake-2.6.4-Linux-i386/bin/cmake  
/project/pomes/cneale/GPC/exe/intel/gromacs-4.5-beta2/src  
-DGMX_OPENMM=ON -DGMX_THREADS=OFF  
-DCMAKE_INSTALL_PREFIX=$(pwd)/gpuexec -DLIB_INSTALL_DIR=$(pwd)/gpuexec
