This repository contains C language headers for the OpenCL API.
The authoritative public repository for these headers is located at:
https://github.com/KhronosGroup/OpenCL-Headers
Issues, proposed fixes for issues, and other suggested changes should be created using Github.
While the headers may just be copied as-is, this repository also contains a CMake script with an install rule to allow for packaging the headers.

target_link_libraries(app PRIVATE OpenCL::Headers)The OpenCL API headers in this repository are Unified headers and are designed to work with all released OpenCL versions. This differs from previous OpenCL API headers, where version-specific API headers either existed in separate branches, or in separate folders in a branch.
By default, the OpenCL API headers in this repository are for the latest
OpenCL version (currently OpenCL 3.0). To use these API headers to target
a different OpenCL version, an application may #define the preprocessor
value CL_TARGET_OPENCL_VERSION before including the OpenCL API headers.
The CL_TARGET_OPENCL_VERSION is a three digit decimal value representing
the OpenCL API version.
For example, to enforce usage of no more than the OpenCL 1.2 APIs, you may include the OpenCL API headers as follows:
#define CL_TARGET_OPENCL_VERSION 120
#include <CL/opencl.h>README.md This file
