libvdwxc: build system and tests (!488) · Merge requests · octopus-code / octopus

This merge request should resolve any remaining issues with the libvdwxc interface so the feature is no longer considered experimental.

Adds m4 file and other infrastructure for linking against libvdwxc through ./configure --with-libvdwxc-prefix=DIR.

Adds two unit tests of libvdwxc: One non-periodic (H2O) and one 3D periodic (primitive Be HCP cell, to verify non-trivial non-orthogonal cells).

See also !431 (closed) (previous version of this merge request) and #122 (closed) (discussion).
