The directory found by CMake
(/System/Library/Frameworks/OpenCL.framework/Headers/) contains only .h
files.
The khronos site mentioned by Denis offers cl.hpp for v1 and cl2.hpp for
v2. qgsopenclutils.h includes cl2.hpp.
Should I download and try cl.hpp on my mac? If it compiles, how can I
test running it.

Hi all,
A recent change added OpenCL. Compilation fails on macOS because
Apple provides v1.2 (macOS 10.13) while QGIS seems to require v2.
That's wierd: 1.1 is what should be required can you file a ticket
and provide full logs?
Adding a version to FIND_PACKAGE will fix the macOS compile and
not use OpenCL.
Apple has deprecated OpenCL in favor of its own Metal
technology. OpenCL will remain for macOS 10.14 (Mojave, fall
2018) but may be removed after fall 2019.
For the future, either OpenCL must remain an optional QGIS
feature in order to support macOS or the API needs to be
abstracted so that macOS can use Metal while other OSs use OpenCL.
OpenCL is an optional feature and there is no plan to change that.
