You probably meant ${QT_QTCORE_LIBRARY} instead of $QT_CORE_LIBRARY
What about this:
find_package(Qt4 4.6.0 COMPONENTS QtCore QtGui QtOpenGL REQUIRED)
include(${QT_USE_FILE})
...
target_link_libraries(plot ${QT_LIBRARIES})
The file pointed to by QT_USE_FILE sets up the current directory with include
directories and compile flags and sets up QT_LIBRARIES for the chosen
components.
You can do it on your own, but its more work.
