Instruction mention to define OPENCL_ICD_LOADER_HEADERS_DIR to include header and has no effect so fails.

Hi, the OPENCL_ICD_LOADER_HEADERS_DIR should be where you've cloned the OpenCL headers, and does not need the CL suffix. Also, this should be a CMake variable, not a shell environment variable. Looking at your output above, can you try:

cmake -DOPENCL_ICD_LOADER_HEADERS_DIR=/git.co/khronos/OpenCL-Headers/ ..

You can also refer to the build setup we use for the Travis CI builds in .travis.yml, if that helps. Thanks!

Hi @ggghamd, can you please confirm that you were able to build the ICD loader following the instructions above? Thanks!
