Subject: gnu: Add dune-uggrid.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* gnu/packages/maths.scm (dune-uggrid): New variable.
(dune-grid)[propagated-inputs]: Add dune-uggrid dependency, so
that the UGGrid class in dune-grid can be used by packages that
have dune-grid as input.
(dune-functions)[arguments]: Enable tests that previously weren't
built as they require dune-uggrid.
