How can I override a parameter in CC_SYNTHESIZE in c++?

Question

as I told, I don't understand how can I override a CC_SYNTHESIZE. I want to remove a warning on this line.

CC_SYNTHESIZE(**int** , idObject, IdObject);

WARNING:
'getIdObject' overrides a member function but is not marked 'override'
'setIdObject' overrides a member function but is not marked 'override'

How can I resolve this? thank you for reading and sorry if is a dumb question
