I download example code in “OpenCL Programming Guide” (by Aaftab Munshi…), but some error occurred while cmake .

Both OPENCL_LIBRARIES and OPENCL_INCLUDE_DIRS were set manually by me. (Not set by installed intel_code_builder_for_opencl_2015_5.0.0.62_x64)
However, I used cmake-gui to cmake is OK:
![]()

It’s seemed that I still not configure environment correctly. Could you give me some advices?
