[CMake] case in IF statements

[Ken Martin]

>From bug id #3119

I looked into this. The issue is that NOT is an argument to the if command
and currently arguments are not case insensitive. To make this change and be
consistent we would need to modify every command in cmake to be case
insensitive to its arguments which might be a good idea, but is a bit of
work and currently not on the agenda. This becomes more confusing for
commands where a file name is an argument because in those cases (for UNIX)
the arguments really are case sensitive.  The same applies to many string
type functions. We could say only keyword arguments to functions are case
insensitive but for now I think it is easiest to leave it as is.
