Using OpenCV with C++

I ran into lots of issues trying to get the SFM example to work with C++, mostly linking errors. Installing Ceres and its dependencies was a breeze. The problem, however, was that the SFM libraries were not detecting Ceres, and so weren’t being included. To fix it, I had to add:

#define CERES_FOUND 1

before I included the SFM libraries. This fixed the SFM issues but I still faced issues with the VIZ module, until I realized I just had not added that dependency to cmake.

Why is cmake so unintuitive to use?
