/** \class cmExternalMakefileProjectGenerator
 * \brief Base class for generators for "External Makefile based IDE projects".
 *
 * cmExternalMakefileProjectGenerator is a base class for generators
 * for "external makefile based projects", i.e. IDE projects which work
 * an already existing makefiles.
 * See cmExtraEclipseCDT4Generator as an example.
 * After the makefiles have been generated by one of the Makefile
 * generators, the Generate() method is called and this generator
 * can iterate over the local generators and/or projects to produce the
 * project files for the IDE.
