Well, I pointed out pocl-opencl-icd because it is in "main" and it
provides a CPU based implementation that seems to be cross platform.
Not sure how well it implements the specs though.
Pulling in non-free packages (like amd or nvidia -icd") during the build
might force you to put the package into "contrib" and these packages
have very limited hardware support.

Less bash, more make:
<<<<<<<<<<<<<<<<
num_opencl_platforms := $(shell clinfo | head -n1 |\
sed -e "s/.*[^0-9]\([0-9]\+\)[^0-9]*$$/\1/")
ifeq ($(num_opencl_platforms), 0)
override_dh_auto_test:
@echo "No OpenCL platform available, skipping test"
else
override_dh_auto_test:
dh_auto_test
endif
