KDE4_ADD_TEST_EXECUTABLE is deprecated now use KDE4_ADD_EXECUTABLE(<target> TEST <files>) instead
QT4_ADD_DBUS_INTERFACE_NO_NAMESPACE and QT4_ADD_DBUS_INTERFACES_NO_NAMESPACE are deprecated too
used SET_SOURCE_FILES_PROPERTIES(<files> PROPERTIES NO_NAMESPACE TRUE) QT4_ADD_DBUS_INTERFACES(<srcList> <files>)
set( EXECUTABLE_OUTPUT_PATH ${CMAKE_CURRENT_BINARY_DIR} ) is put in each CMakeLists.txt where
KDE4_ADD_EXECUTABLE(<target> TEST <files>) and KDE4_ADD_UNIT_TEST were used.
