Sorry. I wrote that email in a hurry on a linux machine and had intended to 
follow up with details when I got back on windows.

After adding qDebug() << args; after both QCoreApplication::arguments() 
calls, here's the output while attempting to compile grantlee:

(grantlee.org if you want to give it a shot. It finally builds! :) )

As you can see, when cmake invokes automake, the path:

C:/software/grantlee/build/grantlee_core_library/grantlee_core_library_automoc.cpp

is split into 

C:

and 

/software/grantlee/build/grantlee_core_library/grantlee_core_library_automoc.cpp

which is where I get breakage. So this looks like a cmake bug to me. When I 
invoke the same command myself, I can successfully run the command.
