[C++][cpp-restsdk] ModelBase.h should be included. Compilation failed

Created by: CyrilleBenard

Description

The generator does not include the ModelBase.h file whereas it generates code that uses a method that is defined in it (see toJson, toHttpContent, ... etc)

The compilation error looks like :
