The concensus seems to be that ExactCase is used. It also makes a lot more 
sense to me for several reasons but that's off topic for this thread. It's 
unfortunate that the ambiguity didn't get resolved in general. 

For Qt5 and config files I think exact case makes even more sense because 
using config files sets ExactCase_FOUND to true if found. 

Thanks,

Steve.
