cannot find CUVID library in driver directory

I have a Tesla GPU P4,. Now i am using it on a server whose CPU architecture is POWER8. I want to use the P4 for video decoding .
The GPU driver I installed is : nvidia-driver-local-repo-rhel7-375.66-1.ppc64le.rpm
The cuda toolkit I installed is: cuda-repo-rhel7-8.0.61-1.ppc64le.rpm
The sytem info :Linux power107.centos73 3.10.0-514.10.2.el7.ppc64le
but i cannot find the which is needed to perform the video decoding. I think the should be installed along with the GPU driver. So I want to know how to acquire the cuvid library?
