OpenCL™ Runtime and Compiler for Intel® Processor Graphics
By default the environment variable INTELOCLSDKROOT is automatically added to the system during installation and points to the OpenCL Runtime installation directory. This directory is also automatically added to the system PATH environment. For more information, please see the OpenCL Runtime Release Notes.
To work with the OpenCL runtime, an application should link to the OpenCL Installable Client Driver (ICD) import library, presented as the OpenCL.lib file. The library resides in the $(INTELOCLSDKROOT)\lib\ directory, under x64 or x86 subdirectory.
