# FindOpenCL
|
|
# ----------
|
|
#
|
|
# Try to find OpenCL
|
|
#
|
|
# IMPORTED Targets
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# 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
|
|
#
