Hi, Did you also install the qt header files? Or do you have more than one Qt installation around?

Unfortunately, I stumbled on a linking problem related to Gist. Apparently there is a problem with linking such library, but I do not know what to do. I downloaded Qt5 and I thought it would be fine, but that is not the case. Do I have to modify anything with CMake? Could you please help me?
