I used the  intel-opencl-r5.0 (SRB5.0) Linux driver package from
https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver.
BTW: I fix a minor issue in the SRB5.0 pkg-config pc file, about
install docs, you can find in
http://registrationcenter-download.intel.com/akdlm/irc_nas/11396/SRB5.0_intel-opencl-installation.pdf
