This may be acceptable since they have the same upstream and upstream doesn't
intend for it to be a shared library.  They will, of course, need to select a
license acceptable for Fedora first, though.  ;-)

These need to be packaged separately and gmsh patched to use the shared
libraries then.

OpenCASCADE's non-freeness is described in detail here:
http://lists.fedoraproject.org/pipermail/legal/2011-September/001713.html

Hmm, gmsh might do better in rpmfusion-nonfree then.  If gmsh will have to be
stripped down so much to be useless to most end users, there's really no point
in shipping it in Fedora proper.

Note that the bundled library policy still applies over at RPMFusion, so that
will still need to be resolved.
