Unable to build on OS X 10.13.2
Hello,
I'm eager to try out xmrig-amd! However, on Mac OS High Sierra (10.13.2) cmake fails to find OpenCL with the output below. Any fixes, workarounds or suggestions are welcome. 
Thanks!

>build (master)$ cmake ..
CMake Warning at cmake/OpenCL.cmake:51 (find_package):
  By not providing "FindOpenCL.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenCL", but
  CMake did not find one.

  Could not find a package configuration file provided by "OpenCL" with any
  of the following names:

    OpenCLConfig.cmake
    opencl-config.cmake

  Add the installation prefix of "OpenCL" to CMAKE_PREFIX_PATH or set
  "OpenCL_DIR" to a directory containing one of the above files.  If "OpenCL"
  provides a separate development package or SDK, be sure it has been
  installed.
