Hi krish_22,
In this link are some steps you can follow to cross compile open cv http://docs.opencv.org/doc/tutorials/introduction/crosscompilation/arm_crosscompile_with_cmake.html .
Also, since you want to work with a cam I suggest you to take a look at this post https://communities.intel.com/thread/48204?start=0&tstart=0 where a user successfully made the cam work using openCV.
Regards,
Sergio
