[meta-freescale] OpenCV OCL module Support on IMX6q

Dear Sebastian,

Thank you for your answer. The header is installed inside sysroot folder.

Actually, our purpose here is to use the GPU for some image/video
processing tasks. We have tested OpenCV on IMX.6q, but for some algorithms,
GPU usage will increase the performance. But, unfortunately, I couldn't
find easy way to use the GPU. That's why I asked for OCL module.

Can I find some image processing examples created with OpenCL for IMX6? I
searched from the web, but I couldn't find anything except hello world

Best Regards,
