[mythtv] Trying to add QJson to mythfilldatabase, failing spectacularly.

[Robert Kulagowski]

QT 4.8, and Json isn't included natively until QT5, so installing qjson to help.

I've added #include <QJson> to filldata.cpp

I've modified mythfilldatabase.pro and added /usr/include/qjson to
INCLUDEPATH and +LIBS += -lqjson

I've installed (on Ubuntu 12.04):

$ sudo apt-get install libqjson-dev libqjson0

make distclean, configure, make.

No joy. :(

What's the special sauce that I'm missing? Various examples found
through Google make it seem as easy as including QJson, but that's not
working for me, and I don't know if it's something obvious, or
something about how the MythTV make file is generated.
