Using OpenCV 3.0

1. Generate OpenCV makefile using cmake (e.g. cmake CMakeLists.txt)
2. Compile using makefile generated at (1) (e.g. make -j8)
3. Install generated files (e.g. make install)
4. Export opencv shared library path:
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
5. Compile your program like this: "g++ [source file goes here] `pkg-list opencv --config`"
