FTBFS with opencascade 7.6.3

opencascade is currently a transition in debian, and since it's a sync, so in ubuntu.

netgen in the kinetic archive was build with opencascade 7.5.2 (currently in kinetic release), and fails to build with opencascade 7.6.2 (currently in kinetic proposed):

/home/ubuntu/git/packages/netgen/netgen/libsrc/occ/occgenmesh.cpp:1158:43: error: ‘class Poly_Triangulation’ has no member named ‘Nodes’; did you mean ‘Node’?
 1158 | p[k-1] = triangulation->Nodes()(n).Transformed(loc);
      | ^~~~~
      | Node
/home/ubuntu/git/packages/netgen/netgen/libsrc/occ/occgenmesh.cpp:1159:45: error: ‘class Poly_Triangulation’ has no member named ‘UVNodes’; did you mean ‘UVNode’?
 1159 | par[k-1] = triangulation->UVNodes()(n);
      | ^~~~~~~
      | UVNode

Debian bug[1] has linked to an upstream fix[2].

This is likely also the cause of the python/pygmsh/gmsh segfault[3] that is blocking the pytest3 migration currently:
