For macOS, copying cl2.hpp from
Setting USE_OPENCL=OFF also works to disable OpenCL.
One or the other is necessary or macOS will try the use the v1.2 C
headers provided by Apple and pointed to by OpenCL_INCLUDE_DIR.
After lanuching QGIS, I see the Options|Acceleration panel with three
Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz
HD Graphics 4000
GeForce GT 650M
To automate the mac build, my suggestion is to create a
OpenCL_HPP_INCLUDE_DIR variable. If a mac user sets it, use OpenCL; if
not, don't use OpenCL. For other platforms, OpenCL_HPP_INCLUDE_DIR is
automatically set to OpenCL_INCLUDE_DIR.
