+# FindOpenCL
+# ----------
+#
+# Try to find OpenCL
+#
+# Once done this will define::
+#
+#   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
+#
