[CMake] BOOL type

To supplement Brandon's Boolean wishlist, I would like to see some way to
specify a non-default precedence of Boolean operators.  Most languages use
parentheses for this, and ideally that would be true for CMake as well.
Then a test of Boolean inequality of A and B would be

IF((A AND NOT B) OR (NOT A AND B))

and a test for Boolean equality of A and B would be

IF((NOT A OR B) AND (A OR NOT B))

Perhaps CMake already has this feature but it is not documented?
