how to differentiate between intransitive verb and incomplete verb

Please read the following sentences:

* The infant sleeps.
* They made him the President.

The first sentence shows complete sense without any help of any other word whereas the sense of second sentence completes only with the help of the word ‘President’.

Intransitive verbs like appear, be, become, get, grow, live, look, seem etc. are generally used as incomplete verb.
