That's what I did at the end. 
I did this:

FIND_PACKAGE(Qt4 4.6.0 COMPONENTS QtCore QtGui QtOpenGL REQUIRED)
INCLUDE_DIRECTORIES(${QT_INCLUDE_DIR} ${QT_QTCORE_INCLUDE_DIR}
${QT_QTGUI_INCLUDE_DIR})
MESSAGE(STATUS "QT_QTCORE_LIBRARY=${QT_QTCORE_LIBRARY}")
TARGET_LINK_LIBRARIES(plot $QT_QTCORE_LIBRARY)

The include dirs are set correctly, but I'm having trouble with
QT_QTCORE_LIBRARY.
This appears as :
QT_QTCORE_LIBRARY=optimized;C:/Progra~2/Qt/4.6.0/lib/QtCore4.lib;debug;C:/Pr
ogra~2/Qt/4.6.0/lib/QtCored4.lib

When I open the solution with vs2008, the Librarian doesn't show this
libraries as input.

Note the help for TARGET_LINK_LIBRARIES displays the syntax as:
target_link_libraries(<target> [item1 [item2 [...]]]
                       [[debug|optimized|general] <item>] ...)

There are no semicolons after the optimized|debug keywords, I wonder if by
not using QT_USE_FILE, QT_QTCORE_LIBRARY are others are set incorrecty.

Rds,
