/** \class cmData
 * \brief Hold extra data on a cmMakefile instance for a command.
 *
 * When CMake commands need to store extra information in a cmMakefile
 * instance, but the information is not needed by the makefile generators,
 * it can be held in a subclass of cmData.  The cmMakefile class has a map
 * from std::string to cmData*.  On its destruction, it destroys all the
 * extra data through the virtual destructor of cmData.
