related to: Unable to compile anymore #377 - fixes bug to compile it with opencv 3.2.0

[TheTesla]

fixes the compile error: /opt/ros/kinetic/include/opencv-3.2.0-dev/opencv2/flann/saving.h:113:63: error: exception handling disabled, use -fexceptions to enable throw FLANNException("Invalid index file, cannot read");

Works like a charm! My configuration:

• Ubuntu 16.04
• ROS Kinetic
• OpenCV 3.2
• CUDA 8.0
• PCL 1.8

Would be good to merge this for everyone who hits this error and has to search for the solution like I just did.

@TheTesla you should also delete the comment that explains the removed line.
