marecki@gentoo.org Marek Szuba The OpenCL API headers in this package 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 supported. 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. KhronosGroup/OpenCL-Headers
