### The OpenCL SDK allows us to build some additional applications

# NOTE: We prioritize the OpenCL SDK compared to the regular OpenCL in
# order to avoid picking the system OpenCL. This is because the OpenCL
# library seems to have a dependency on some scripts that ship with
# the SDK, which is not installed on the system. So if the person who
# installed the system OpenCL library deleted his/her SDK source, we
# will be in trouble.
