Please set both for the moment.

I don't remember why there are two variables for the same thing.
I'll try to clarify that in the next OTB release and keep only one 
variable, and make FindGDAL.cmake recognize William's framework 
automagically.
We are currently using the default FindGDAL provided by cmake.

OK, needs some clarification too, I agree the message is not clear enough.

Actually, OTB cannot build with external ITK version in its current state.

The only thing we really need as external library is GDAL, which you get from William's framework.
For the rest, default system libraries should be ok (expat, curl...), and internal version for the rest is ok too.
