You are right. Since Opencascade ships many libs, I usually rely on
inter-library
dependencies to minimize the number of -l flags, but this is poor practice.

Here is an updated patch to remove only unused libs, it is based on
  https://buildd.debian.org/fetch.cgi?pkg=gmsh;ver=2.3.1.dfsg-2%2Bb1;arch=amd64;stamp=1243847669
