+# 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
+#
