Error when compiling on computers with Nvidia GPU

[gocarlos]

On some computers with NVIDIA GPU there is an error when compiling.
On a workstation with a Quadro K2100M it works, on another with a GTX 670 it does not.
Both have CUDA installed as seen when run the compilation with "-v". On both Ubuntu 14.04.05.
It works if compiled without CUDA support.

Eventually it would be a good thing to make the tests on a machine capable of CUDA.

On the computer, which has problems with CUDA, this script runs fine.

@gocarlos A simple hack is to put the following line just before cuda_compute_capability check which could be easily found by checking your GPU compute capability(which was 3.5 in my case).
set(CUDA_COMPUTE_CAPABILITY 3.5)

Still I receive the following error
string sub-command REPLACE requires at least four arguments.

which I think is because the in string function is empty. So to make it work I did another hack of using CUDA_ARCH instead of CUDA_ARCH_LIST in the following for loop.
My CMakeLists.txt after making changes is as this. It would be great if you could make the pull request with your permanent fix to such problem.

@arpit15 I didn't find a solution for that problem so far, currently I'm using Infinitam without CUDA (#set(WITH_CUDA FALSE) in CMakeLists.txt) .

is your solution working then with CUDA? have you seen if its using CUDA when you start it?

Hi @gocarlos did you solve the problem when its using CUDA?

humm, this was 3 years ago... I don't remember if I had a solution...
I'm not working in robotics anymore...
