ElmerGUI fails to build when using OCC

[GenericNerdyUsername]

I'm trying to migrate a package repository away from using OCE as it is no longer maintained, but compiling with OCC and -DWITH_ELMERGUI:BOOLEAN=TRUE on commit d1d4983 causes the compile to fail with the error

/build/source/ElmerGUI/Application/cad/cadview.cpp:365:54: error: 'class Poly_Triangulation' has no member named 'Nodes'; did you mean 'Node'?
  365 |     const TColgp_Array1OfPnt &Nodes = Triangulation->Nodes();
