[CMake] GUIDs in VS solution files

[Bill Hoffman]

I just checked a fix into CVS, that reads the GUID from  an external 
project and uses that instead of generating a new one.  (caused an error 
with VS 2005 SP1).  You may want to update and start with that code.   
The code uses an XML parser, so you should be able to figure out the 
type of external project as well without changing too much.
