STRINGS

Enumerate possible STRING entry values for GUI selection.

For cache entries with type STRING, this enumerates a set of values. CMake GUIs may use this to provide a selection widget instead of a generic string entry field. This is for convenience only. CMake does not enforce that the value matches one of those listed.
