Subject: [bug#43761] [PATCH v4] gnu: gmsh: Update to 4.6.0.

From: zimoun <[email-masked]>
Date: Mon, 5 Oct 2020 15:58:01 +0200

Gmsh bundles METIS 5 released with Apache License 2.0 since upstream commit
eaff7f6477fe876991615cfa4b5832bd5f12994b.  Instead, Gmsh is linked with the
package 'metis'.

* gnu/packages/maths.scm (gmsh): Update to 4.6.0.
(propagated-inputs): Replace 'opencascade-oce' by 'opencascade-occt', add
'metis'.
