[Cmake] cmake bug with IF statement and end-of-line comment

[Bill Hoffman]

It used to be that the comments had to be on a separate line, and it
was not documented.  However, I have just changed that, and now you 
can have comments anywhere.

In all previous versions of cmake, putting comments in the middle of 
a line caused unpredictable results.
