Hello! I have a project in which I need to use Ubuntu 14 with ROS Indigo. ROS Indigo includes OpenCV 2.4 so I'm using that version in order to avoid possible compatibility problems when connecting them. As I need to implement Feature Detection functions, I read that I could use OpenCV. The problem is that as I'm new in this field, I don't know what libraries/packages I need to add in order to compile code with, for example, these functions; https://docs.opencv.org/2.4/modules/features2d/doc/feature_detection_and_description.html
I've also seen the tutorial: https://docs.opencv.org/master/d9/d97/tutorial_table_of_content_features2d.html But I also have the problem: not knowing how to make de CMakeLists.txt file to compile it.
Thank you very much for your help!
