You should keep both opencv/opencv_contrib repositories "in sync".

sorry, I don't quit understand. Do you mean this?
CMake Error at C:/opencv/opencv_contrib/modules/text/CMakeLists.txt:22 (ocv_add_testdata):

I mean you should run git fetch/pull for both opencv/opencv_contrib repositories.
For more questions please please refer to GitHub manuals at first.

@vsmelov , modules/text/CMakeLists.txt does not contain ocv_add_testdata command in version 3.1.0, it means something is wrong with your opencv_contrib repository.

@mshabunin you are right , the text file must not contain ocv_add_tesdata command however I did not realize that since i delete it from the text file .Then it has worked .
Thx for reply
