I wrote my own FindQt4 so that I can easily do things like this:

SET(sources
  main.cc
  MainWindow.cc	MainWindow.h
  resources.qrc
  MyDialog.ui
)
QT_ADD_EXECUTABLE(exe ${sources})
TARGET_LINK_LIBRARIES(exe ${QT_GUI_LIBRARY})

QT_ADD_EXECUTABLE can handle resources, user interfaces (not working yet) and 
moc.
My problem is with .ui files. I want cmake handle .ui files the way qmake 
does. QMake will only generate the ui_MyDialog.h if one of the source file 
includes that file.

I wrote this macro to make MainWindow.cc depending on ui_MyDialog.h
QT_UI_DEPENDS(MyDialog.ui MainWindow.cc). I think QT_ADD_EXECUTABLE should 
handle everything.
