-# Once done this will define
-#  OPENCL_FOUND        - system has OpenCL
-#  OPENCL_INCLUDE_DIRS  - the OpenCL include directory
-#  OPENCL_LIBRARIES    - link these to use OpenCL
+#   OpenCL_FOUND          - True if OpenCL was found
+#   OpenCL_INCLUDE_DIRS   - include directories for OpenCL
+#   OpenCL_LIBRARIES      - link against this library to use OpenCL
+#   OpenCL_VERSION_STRING - Highest supported OpenCL version (eg. 1.2)
+#   OpenCL_VERSION_MAJOR  - The major version of the OpenCL implementation
+#   OpenCL_VERSION_MINOR  - The minor version of the OpenCL implementation
+#
+# The module will also define two cache variables::

+#   OpenCL_INCLUDE_DIR    - the OpenCL include directory
+#   OpenCL_LIBRARY        - the path to the OpenCL library
