[License] PDAF is LGPLv3
The PDAF license is the GNU Lesser General Public License version 3 and we link statically against it which is not allowed with the current Melissa license (BSD). Relicensing is nontrivial because Inria is not the sole copyright holder (Énérgie de France contributed, too).
The easiest solution is to build PDAF as a shared library and link against it dynamically.
