I guess Cmake isn't detecting OpenCL on your system. You might have to run
'cmake-gui' in order to point to the place where the OpenCL include files
(e.g. CL/cl.h) and libraries (libOpenCL.so) are located in your system.
Did you do basic tests to see if OpenCL is correctly installed? You can
check that out with the 'clinfo' command (there's a Debian package for it
and if you don't have a package its easy to compile).
Unless BRLCAD_ENABLE_OPENCL is ON the OpenCL host code will be #ifdefd out
and won't be compiled at all.

OpenCL 1.2 loads the .cl device code source files at runtime and compiles
them at runtime. This is often done by the driver kind of like compiling
GLSL shaders.
