Yes, this a problem.   It should work by doing this:

find_package(Qt4 required)

target_link_libraries(target ${QT_LIBRARIES})

There are some options for the QT_USE_FILE:

# QT_USE_FILE which is the path to a CMake file that can be included to compile
# Qt 4 applications and libraries.  By default, the QtCore and QtGui 
# libraries are loaded. This behavior can be changed by setting one or more 
# of the following variables to true:
#                    QT_DONT_USE_QTCORE
#                    QT_DONT_USE_QTGUI
#                    QT_USE_QT3SUPPORT
#                    QT_USE_QTASSISTANT
#                    QT_USE_QTDESIGNER
#                    QT_USE_QTMOTIF
#                    QT_USE_QTNETWORK
#                    QT_USE_QTNSPLUGIN
#                    QT_USE_QTOPENGL
#                    QT_USE_QTSQL
#                    QT_USE_QTXML

CMAKE_INSTALL_PREFIX is where the current project will be installed.
The default value for that is /usr/local.
