Opencl Runtime Kali Linux – Super User

I'm trying to run hashcat on Kali Linux. Whenever I run it, I get this error:

                Device # 1: Not a native Intel OpenCL runtime environment. Expect a massive loss of speed.
You can use --force to replace, but do not report associated errors.

I know I can use –force to cancel this and run it at a slower speed. But how can I install openCl and run it at its maximum speed?
