Comment(by hamish):

 I've got these headers in the /opt/AMDAPP/include/CL directory; which
 should we search for as part of the ./configure --with-opencl check?

 {{{
 cl.h
 cl.hpp
 cl_ext.h
 cl_gl.h
 cl_gl_ext.h
 cl_platform.h
 opencl.h
 }}}


 my i7 3770 intel driver is not a Xeon, so no OpenCL support for linux yet,
 and my nvidia system + proprietary driver supplies:
 {{{
 /usr/lib/libOpenCL.so
 /usr/include/nvidia-current/CL/cl.h
 /usr/include/nvidia-current/CL/cl_platform.h
 /usr/include/nvidia-current/CL/cl_gl.h
 }}}

 from the nvidia-current-dev package.


 so the 3 header files from the nvidia package seem to be the common ones
 to check for. maybe cl.h is enough to look for?
