Hi, It fails to find CUDA 5.0. See below.
$ env | grep CUDA
CUDA_PATH=/cm/shared/apps/cuda50/toolkit/5.0.35
CUDA_INC_PATH=/cm/shared/apps/cuda50/toolkit/5.0.35

CUDA_CACHE_DISABLE=1
CUDA_INSTALL_PATH=/cm/shared/apps/cuda50/toolkit/5.0.35
CUDA_ROOT=/cm/local/apps/cuda50/libs/304.54
$ cat ../CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(CheckCUDALibs)
find_package(CUDA)
message(STATUS "CUDA_LIBRARIES = ${CUDA_LIBRARIES}")

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

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?
