I agree. Then we will be able to package the various plugins and distribute 
them.

No need to clutter it up. There is the environment variable HDF5_PLUGIN_PATH. 
From the HDF5 filters doc [1]:

For now I'd rather stay with the above default configuration, until new real 
life cases are submitted.

Should be easy to do, I guess.

Otherwise, would it be possible to add local plugins folder ?
Something as:

- 
--with-default-plugindir=/usr/local/lib/$(DEB_HOST_MULTIARCH)/hdf5/plugins:/usr/lib/$(DEB_HOST_MULTIARCH)/hdf5/plugins

Just for information do we have this plugin directory available in the 
pkg-config file in order to setup
the plugging directory for a third-party plugging project ?

I've juste uploaded release 1.10.0-patch1+docs-1~exp3 to experimental,
configured with:
--with-default-plugindir=/usr/lib/$(DEB_HOST_MULTIARCH)/hdf5/plugins

Could you please give it a try?

Thanks,

Bug#826522: Set the plugin directory

Dear HDF5 package maintainers,

Currently the debian build system does not enforce the plugin directory
for HDF5 filters, defaulting to "/usr/local/hdf5/lib/plugin". I guess
Debian would prefer something like:
"/usr/share/hdf5/plugin" or even better:
"/usr/lib/x86_64-linux-gnu/hdf5/plugins".

Would it be possible to specify the option 
--with-default-plugindir=/usr/lib/x86_64-linux-gnu/hdf5/plugins
to ./configure in order to re-locate those plugins and offer in
external packages those plugins.

At synchrotrons, some of our detectors use LZ4 compression in HDF5
files. Having plugins packaged and directly installable is real
advantage compared to other operating systems.

Thanks for you comprehention.
With my best regards,

Jérôme Kieffer
