Opencv installation, usage with and without ROS
Hello, I have OpenCV 2.4.8 which was installed along with ROS Indigo on an Ubuntu 14.04. My project requires use of OpenCV 2.4.9. I have limited understanding of how this installation works. I have seen a few questions and answers related to this. But it is still not clear to me. So, I have a few questions:
Can I install OpenCV 2.4.9 by following the normal installation method? If I do so will it break the version (2.4.8) linked with ROS Indigo?
If I get OpenCV 2.4.9 installed, how can I get it to work with ROS Indigo? Also, once linked how to get it back in standalone mode?
