CMake und Qt Testmodul

Hallo,
ich hab folgendes Problem: ich wollte ein einfaches Beispiel mit cmake basteln, das einen UnitTest mit der Qt Test Library kompiliert. Ich hab das Teil zuerst mit einer *.pro-Datei kompiliert, hat geklappt. Allerdings ergibt der Lauf mit dem von CMake generierten Makefile einen Linkerfehler. Wäre schön, wenn jemand eine Lösung findet, im Web hab ich leider kein Beispiel gefunden.

Die CMake-Datei die nicht funktioniert:

project(MoneyTest)

cmake_minimum_required(VERSION 2.6.0)
find_package(Qt4 REQUIRED)
include( ${QT_USE_FILE} )

set(QT_USE_QTTEST TRUE)

set(project_SRCS
  Money.h
  Money.cpp
  MoneyTest.cpp
  MoneyTest.h
)
set(project_MOCS
  MoneyTest.h
)

qt4_wrap_cpp(project_SRCS ${project_MOCS} )

include_directories(${CMAKE_CURRENT_BINARY_DIR})

add_executable(MoneyTest ${project_SRCS})
target_link_libraries(MoneyTest ${QT_LIBRARIES})

Fehlermeldung des Compiler/Linker
