HeeksCAD fails to build against OCE 6.8.0

[danieloneill]

Trying to build against OCE found in Github, though I'm not sure how legitimate it is. It appears fairly well maintained.

Regardless, it fails to compile here:

/home/doneill/cnc/heekscad/src/ConversionTools.cpp: In function ‘bool ConvertEdgeToSketch2(const TopoDS_Edge&, HeeksObj*, double, bool)’:
/home/doneill/cnc/heekscad/src/ConversionTools.cpp:634:4: error: ‘Mesh’ is not a member of ‘BRepMesh’
    BRepMesh::Mesh(edge, deviation);

According to the OpenCascade documentation as of at least 6.8.1 the method has been missing.

As per this thread, replacing BRepMesh::Mesh with BRepMesh_IncrementalMesh fixes this.

These are all the changes I had to make to HeeksCAD in order to get it compiled:
