* \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.
