This looks like the submodule hasn't been initialised. You either need to pass the --recursive flag when you clone the repository, or run git submodule update --init in an existing clone.

Enabled submodules but end up with issues ..

It looks like you're missing the definitions for OpenCL 2.x features. Are you building against the latest OpenCL C headers? The latest headers are always available here:

Hello! We found this issue as part of a recent issue scrub and we think this issue is no longer occurring. Please refer to the steps followed by the automated CI testing if you are still (after four years 😄) having issues building. Thanks!
