Errores en archivos MOC generados para QT5 desde cmake

Generé archivos moc para QT5 usando

set (CMAKE_AUTOMOC ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)

Luego agrego los archivos moc en SRC usando

SET(SRC
  src/main.cpp
  src/video_widget_surface.cpp
  src/video_widget.cpp
  src/video_player.cpp
#moc files
  moc/moc_video_player.cpp
  moc/moc_video_widget.cpp
  moc/moc_video_widget_surface.cpp

Finalmente agrego el ejecutable usando

add_executable(somegui ${SRC})

Pero me dan errores en los archivos moc que dicen:

Mi entendimiento es que hay algún error en los archivos moc que se crean. Pero no tengo ningún control sobre cómo se crea eso. Ahora, ¿cómo resuelvo este error?
