I have had no problem with Ubuntu 12.10 and Cuda 5; findCuda is able
to find cuda in /usr/lib. Can you run CMake --debug-output output
enable and see where findCuda is searching?

Hi Robert,
I agree that on the CentOS machine the install paths are non-standard. For
the Ubuntu system, on the other hand, I have to disagree with that
statement. It is a *standard* Ubuntu 12.10 system, so IMHO FindCUDA.cmake
should be able to locate libcuda.so on that system.
Regards,
Marcel Loose.

You have a nonstandard install path that will require you to use
CUDA_PATH / CUDA_BIN_PATH and CUDA_LIB_PATH.

Only when explicitly setting CUDA_LIB_PATH, libcuda.so is found.
BTW: On Ubuntu I also need to set CUDA_LIB_PATH, but then to
/usr/lib/nvidia-current.

Marcel Loose.

Can you provide what Cuda version FindCuda is failing to find, and
where Cluster Manager is installing the CUDA toolkit and library?

Hi all,
I noticed that FindCUDA.cmake fails to locate libcuda.so on at least
two
different platforms: Ubuntu 12.10 and CentOS 6.3 using Cluster Manager
v5.2.
I can persuade FindCUDA.cmake to search for this library by explicitly
setting the environment variable CUDA_LIB_PATH, and then it finds it.
However, IMHO, using this trick should only be necessary as a last
resort.
Is this a bug?
Best regards,
Marcel Loose.
