/** \brief Represents a cmake invocation.
*
* This class represents a cmake invocation. It is the top level class when
* running cmake. Most cmake based GUIs should primarily create an instance
* of this class and communicate with it.
*
* The basic process for a GUI is as follows:
*
* -# Create a cmake instance
* -# Set the Home & Start directories, generator, and cmake command. this
* can be done using the Set methods or by using SetArgs and passing in
* command line arguments.
* -# Load the cache by calling LoadCache (duh)
* -# if you are using command line arguments with -D or -C flags then
* call SetCacheArgs (or if for some other reason you want to modify the
* cache), do it now.
* -# Finally call Configure
* -# Let the user change values and go back to step 5
* -# call Generate
* If your GUI allows the user to change the start & home directories then
* you must at a minimum redo steps 2 through 7.
