[CMake] Windows drive letter capitalization consistency

[James Bigler]

OK, I'm not sure if I can provide a reproducing case, because I'm
dealing with a large system that generates code while dynamically
maintaining dependencies.

I did, however, discover something when trying to narrow down the problem.

If I put c:\path\to\source in "Where is the source code" box in the
CMake gui, I get the problem with the inconsistent drive letters.
Putting "C:\path\to\source" produces good behavior.

The only way to get a lower case 'c' is to type it in by hand (perhaps
from another application), because if you use the "Browse Build.."
button it returns upper case drive letters.

Should I file a bug to make the GUI force the drive letter to be uppercase?
