Replacing Makefile with a shell script for OpenCV installation

[NachtSpyder04]

Users who have freshly installed Ubuntu on their laptops may not have make , g++ or other essentials installed. To mitigate this problem, that may look simple but can create problems for those who are new to Linux environment, I suggest replacing Makefile with a shell script ( .sh script like we are using for Wall-E and MARIO) which will update their system as well as install the build-essential package on their laptops along with usual installation of OpenCV as well as its dependencies

Thank You
