[CMake] CMake GUI suggestion - saving/restoring configurations

[Edward Diener]

It would really be nice if the CMake GUI program could save and restore 
configurations for whatever CMake setups the end-user uses. By this I 
mean the ability to save the paths to the source code and where the 
binaries should be built, as well as its corresponding cache 
information, under a user-defined name; and subsequently restore that 
information once the end-user chooses that user-defined name from a 
drop-down list of those that have been saved.

This would enable as many configurations as the end-user uses CMake for 
in an easily usable way using the CMake GUI program.

Another welcome improvement to the CMake GUI would be a drop-down list 
or combobox whenever an item has a set of values to choose from, with 
the CMAKE_BUILD_TYPE being an example of such a field.

The CMake GUI is a great program for using CMake and I hope my 
suggestions can make it better.
