/** \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 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 home directories then
|
|
* you must at a minimum redo steps 2 through 7.
