[Cmake] cmSourceFile.cxx -- when a file cannot be found, two messageboxes are displayed (instead of one)

[ebmiddlecamp at imation.com]

Quick comment:

In "cmSourceFile.cxx", at the end of function "cmSourceFile::SetName()",
the code is written to display two messageboxes if CMake cannot find a
file: one which indicates the file cannot be found, and one which indicates
the extensions used in the search. If you're actually interested in paging
through the messages and reading them, it's difficult. I propose that the
two error messages can easily be combined into one message, which is more
legible and easier on the eyes..

The change only affects a couple of lines; see the attachment for a sample
implementation -
