[Cmake] SOURCE_FILES default extension

[Geoffrey Cross]

I agree with Bill L: I think it should be mandatory to put an extension
on the file name.  Can't we provide a script which will fix the
cmakelists and give a warning for a short while before breaking
projects?  As with VXL, there are inevitably going to be times when you
need to break things for the sake of sanity, and I think this is an
example.
