Hey guys,
Here's an example script that may (or may not!) illuminate things
somewhat:

I think the main point of having VARIABLE in the get_property signature
is to test whether or not a variable is SET or DEFINED with the uniform
api of get_property. It may have been added/implemented simply because
it was easy to do given its implementation.
I agree it's a weird way to set a variable... But it is a nice way to
test for a variable's set-ness without worrying about the whole
confusion that arises from using "if" tests with variable names and
strings in the cmake language. Especially if a variable contains
another variable's name as its contents...
HTH,
David C.
