Unsolved Having problems including QTHelp

[Inchiquin]

I'm trying to add a QHelpEngine to my project, using Qt 4.7.4. When I try to compile I'm getting a slew of "unresolved external symbol" errors. It would appear that it's not including the QtHelp4.lib but I can't seem to add this to the project. I can add other modules, such as Network or Svg, but when I add 'help' to the QT += line in the Project file and run qmake, it doesn't make it into the makefile. I've tried editing the makefile directly but it just reverts to its previous contents when I try to build. Any suggestions?

Try manually linking adding the full path to QtHelp4.lib to the LIBS variable

Ah, that seems to have done the trick. Still curious about why that particular module needed to be manually linked but others didn't, but hey it works, so many thanks.
