Hi,

Could you please look at compilation errors? (http://build.opencv.org/builders/precommit_macos/builds/4156)

Anatoly,

Could you please look at the pull request?

It conforms to other ocl perf tests but doesn't conform to all non-ocl OpenCV perf tests.
So for now it's 👍 , but in nearest future all the ocl perf tests need to be refactored and implemented based on gtestand perf frameworks...
