I tried this
cd /usr/lib/x86_64-linux-gnu
sudo ln -s ../beignet/libcl.so libOpenCL.so
Running "darktable -d opencl" gives:
[opencl_init] trying to load opencl library: '<system default>'
[opencl_init] opencl library 'libOpenCL' found on your system and
loaded
[opencl_init] found 1 platform
[opencl_init] found 1 device
[opencl_init] discarding device 0 `Intel HD Graphics Family' due to
insufficient global memory (0MB).
[opencl_init] no suitable devices found.
[opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.
[opencl_init] initial status of opencl enabled flag is OFF.
Which looks promising. I don't know what 'global memory' refers to
though. I guess this could either be graphics card memory or something
in DT.
Thank you, that's the right symlink. I'm almost there:

But the memory available should be 256MB:
