It should be something more like this...

PROJECT( QtApp )

INCLUDE (  ${CMAKE_ROOT}/Modules/FindQt4.cmake  )
INCLUDE(   ${QT_USE_FILE}   )

SET(QtApp_SRCS main.cxx mainwindow.cxx)
SET(QtApp_MOCS mainwindow.h)
SET(QtApp_RCCS application.qrc)

# generate rules for building source files from the resources
QT4_ADD_RESOURCES(QtApp_RCC_SRCS ${QtApp_RCCS})
# generate rules for building source files that moc generates
QT4_WRAP_CPP(QtApp_MOC_SRCS ${QtApp_MOCS})

# build sources, moc'd sources, and rcc'd sources
ADD_EXECUTABLE(  QtApp ${QtApp_SRCS} ${QtApp_MOC_SRCS} ${QtApp_RCC_SRCS})

TARGET_LINK_LIBRARIES ( QtApp ${QT_LIBRARIES}  )
