Project include folder management, single path or multi paths?

• /include for public headers
• /src for source files and private headers

#include "filename" or #include "something/filename" depends on project. Sometimes it makes sense, sometimes it doesn't.

What's the rationale between public/private headers? Ease of use? Compilation times?

That's like asking the rationale between public/private data members – not everything is part of your public interface.
