This change adds a test for locating libcuda as a driver library. This includes a failing test on a system where libcuda.so.1 is in the ldcache, but not at one of the predefined library search paths. A testdata folder with sample root filesystems is included to test various combinations. Signed-off-by: Evan Lezar <elezar@nvidia.com>
