I don't see where automatically setting ExactCase_FOUND improves over the 
current situation.

Right now, as a user of a Find-module you can only rely on the variables as 
documented for each Find-module.

With automatic setting, you still can only rely on the documented variables, 
since it is only a (to the user unknown) subset of Find-modules which 
additionally sets the undocumented ExactCase_FOUND variable.

Would
find_package(BZip2)
set BZip2_FOUND with the patch ?
Nobody can know without looking at the code of FindBZip2.cmake
