Don,
Few things you could try if you aren't bored already ;-)
1) man cmake
and search for QT4_WRAP_UI
2) replace the examples/qosgwidget/CMakeLists.txt by the one attached to
this mail
when calling ccmake it will pop up a message telling whether or not QT4 was
found (this could be the problem if cmake finds qt3 and not qt4 as the macro
QT4_WRAP_UI is qt4 specific)
3) if in 2) you get that qt4 was not found you can try to uncomment the
first line of the attached CMakeLists.txt but I don't know if it will help.
I hope we can solve this.
Loïc
PS: I just noticed I was replying to Don only by mistake. So it must be hard
to follow this thread for others. Sorry about that.
