Thanks, that's done!
I wanted to confirm if simply changing code in build directory would work
or do we have to recompile with cmake again for changes to be implemented?
I've made all the necessary changes as in patch file and the code also
doesn't seem to have any error. I've tried many things, but still I'm not
getting its openCL rendering as expected (blank .png image, basically). Can
you please check with updated superell_OCL.patch and let me know where I
went wrong?
