I was going to suggest the same. The 

 "C:\Program Files\hdf5-1.8.11\cmake\hdf5\hdf5-config.cmake"

file should contain find_package(mpi), if that is needed.

As far as I understand the issue, I agree. Even if the new features were 
used for another reason, the need for the find_package would still be there.
