You can use our Platform Support page to see what minimum driver versions are required from Intel. This is currently 1.2.0.25 for CPU and 19.13.12717 for GPU. Also check the notes on that page too.
For POCL, there is “expermental” support for SPIR and “even more experimental” support for SPIR-V. This page has some limited information. Unfortunately I have never tried POCL with ComputeCpp so I can’t offer too much advice.
