* cmCommand is the base class for all commands in CMake. A command
* manifests as an entry in CMakeLists.txt and produces one or
* more makefile rules. Commands are associated with a particular
* makefile. This base class cmCommand defines the API for commands
* to support such features as enable/disable, inheritance,
* documentation, and construction.
