I need to install opencv extra modules.. so I followed the steps given :https://github.com/opencv/opencv_contrib
I did: C:\Users\research lab>cd C:\opencv3.1\build
C:\opencv3.1\build> cmake -DOPENCV_EXTRA_MODULES_PATH=C:\opencv_ex\opencv_contrib-master\modules C:\opencv3.1\sources
I got:-- Configuring done -- Generating done -- Build files have been written to: C:/opencv3.1/build
but when i run : make-j5 i got an error : no targets specified and no makefile found..
I checked my build folder, no MAKEFILE was there . WHY is it happening? does makefile is not being generated or some other issue is there?????
