Hello, I'm using OpenCV 4.0.0 and trying to run the code here link text with Visual Studio 2015. I'm quite new in this OpenCV field and C++. In the tutorial folder, there are many cpp and header files 
,
which ones should I add in my project? I know if a '.cpp' file includes specific header files, i should add/create that header file in my project. I tried to add the 'main_detection.cpp' and its following header file, but when I click debug it gives me this error
.
Either I didn't include the right '.cpp' and '.h' files, or I didnt put the correct path for the Data file ( box.ply, box.mp4 etc), or even both mistakes. Hopefully my question was understandable, and I appreciate any help given.
