// 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:
|
|
//
|
|
// 1) Create a cmake instance
|
|
// 2) 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.
|
|
// 3) Load the cache by calling LoadCache (duh)
|
|
// 4) 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.
|
|
// 5) Finally call Configure
|
|
// 6) Let the user change values and go back to step 5
|
|
// 7) 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.
|
|
