Better finding of the hdf5.h include path 
The `FIND_PATH` function has a non-intuitive order in which is searches for include paths and the original form could find a system-installed version of HDF5 even though the developer specified an explicit path via `HDF5_INCLUDE_DIR`.  See https://cmake.org/cmake/help/latest/command/find_path.html for more information.

The form in this patch is the recommended method from that page for changing the default search order to find the explicitly specified path *first*


> The default search order is designed to be most-specific to least-specific for common use cases. Projects may override the order by simply calling the command multiple times and using the NO_* options:
```
find_path (<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_path (<VAR> NAMES name)
```
> Once one of the calls succeeds the result variable will be set and stored in the cache so that no call will search again.
