FindOpenCL
----------
.. versionadded:: 3.1
Finds Open Computing Language (OpenCL)
.. versionadded:: 3.10
Detection of OpenCL 2.1 and 2.2.
IMPORTED Targets
^^^^^^^^^^^^^^^^
.. versionadded:: 3.7
This module defines :prop_tgt:`IMPORTED` target ``OpenCL::OpenCL``, if
OpenCL has been found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables::
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
