QJson* classes not found in QtCreator 3.0.1
I just re-installed Qt 5.2 on my Arch Linux computer. When I fired up QtCreator 3.0.1 and the project I was working on, I'm getting the error: "QJsonDocument: No such file or directory". the line I used was "#include <QJsonDocument>" I tried to find it using a new #include line and the autocomplete options, and it appears that none of the JSON classes are found. The project file does include "QT += core", so I'm not sure why this working on my prior version of Qt Creator (which I can't find anymore, so I don't recall exactly what version of Qt/Qt Creator I was using previously (I know it was at least Qt5).
FYI: I installed this into my /Share/Qt5 directory (/Share is a shared drive between Windows and Linux. I installed there due to the amount of space I have free). When I look in /Share/Qt5/5.2.1/gcc_64/include/QtCore, I do see the header files.
Although I'm guessing I could explicitly point to that particular directory, I do plan on sharing this eventually with others, and I sincerely doubt others would have a /Share/Qt5 directory, so i want to get Qt Creator to acknowledge the files in the normal manner. Can anyone help me figure out how to do that?
