add necessary environment path by

PATH=/path/to/cuda/bin:$PATH

and

LD_LIBRARY_PATH=/path/to/cuda/lib64:$LD_IBRARY_PATH

and export the paths. Alternatively, one can modify /etc/profile to set the environment paths. Add

export PATH="/path/to/cuda/bin:$PATH"

and in commond line type

source /etc/profile

verify the installation. Change directory to CUDA sample and make the samples. Run a sample

sudo ./deviceQuery

to verify the installation.
