For whatever reason I cannot access some functions of cv::ocl, such as cv::ocl::convertfromimage. The compiler is telling me it is not a function of cv::ocl, and when I look at ocl.cpp it isn't there, but I've seen it in the online repositories for ocl.cpp... why would it not show up in my local installation? Is there something I need to do when I build 3.0? an option I missed, or is there an equivalent function that does the same thing? Thanks!

I noticed in the build info that OpenCL is using a 1.2 folder from within OpenCV 3.0, I could not find a way to specify another location... does that need to be changed?

Here is the build information:
