In fact I'd be surprised if the behavior of the file(glob) function is different than using the same wildcards with ls/dir on a terminal.

the cmake glob is different from the results of a terminal ls.

Maybe I was unclear about this, but cmake glob ignores the case regardless of the FS being case sensitive or not.

As you hinted at above, I am not really sure if this really is a bug (:
