It looks like you used the ubuntu cuda package which installs the cuda<br>
library to a directory that FindCUDA wasn't expecting. I think we can<br>
extend FindCUDA to also use x86_64-linux-gnu as a valid directory to<br>
search for libcuda.<br>
<br>
can you submit a bug on mantis for this, so it doesn't get forgotten?<br>

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

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

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

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

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

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