Should the nc-config --libs output show the hdf5 libraries that need

If you have a shared library build, these other libraries are not
included, because they are not needed.
it is not always true that in the shared library "libnetcdf.so"
is written that libhdf5 is necessary. Here is the output of
ldd on our libnetcdf.so":

How should any application know that it has to link with libhdf5?
So we had to edit nc-config to include hdf5 with shared libraries...
