I see.

In that case, could someone provide a diff of the relevent header as it is
included in this system vs khronos headers?

If the differences relatively to khronos headers are small, we may consider
patching the khronos headers whenever they are refreshed (as done with
other headers).

If that proves unpractical, then we need to add more brains to the CMake
files to prefer system headers when available/told...
