You must be doing something wrong. I have been using this macro for ages:
MACRO(QT_ADD_MOC output)
  GET_DIRECTORY_PROPERTY(_flags DEFINITIONS)
  SEPARATE_ARGUMENTS(_flags)

  GET_DIRECTORY_PROPERTY(_includes INCLUDE_DIRECTORIES)
  FOREACH(_dir ${_includes})
    LIST(APPEND _flags ${CMAKE_INCLUDE_FLAG_CXX}${_dir})
  ENDFOREACH()

  FOREACH(_header_file ${ARGN})
    GET_FILENAME_COMPONENT(_header_file ${_header_file} ABSOLUTE)
    GET_FILENAME_COMPONENT(_basename ${_header_file} NAME_WE)
    SET(_moc_file ${CMAKE_CURRENT_BINARY_DIR}/moc_${_basename}.cpp)
    ADD_CUSTOM_COMMAND(
      OUTPUT  ${_moc_file}
      COMMAND ${QT_MOC_EXECUTABLE} ${_flags} -o ${_moc_file} ${_header_file}
      DEPENDS ${_header_file}
      )
    LIST(APPEND ${output} ${_moc_file})
  ENDFOREACH()
ENDMACRO()
