Adaption of Salome Geometry module into an independent library

to compile with OpenCASCADE, an industrial quality open source CAD kernel, without the whole Salome , an open source full-featured CAE platform with GUI and python scripting), just like SMesh, an extraction of Salome mesh module.

Salome Geometry module

Introduction of Geometry module

Salome 9.x has the Shaper module, more dev may go into that new module

adapted features from Salome v9.3

GEOMAlgo: BoundingSphere, BndBoxTree, Gluer, classifier, FinderShapeOn
ShHealOper: fillHoles

what is the difference between OCCT's shape healing algo in TKShHealing toolket

Todo:

OCC2VTK: may not quite necessary, as OCCT has such features
ShapeRecognition: depends on OpenCV, but it does not output TopoDS_Shape

Tested occt version

It should work with OCCT 7.x, but probably not with the community edition (OCE)

Process of adaption

modification on `CMakeFiles.txt`

After commenting out "GetInPlaceAPI.cxx" in CMakeFiles.txt, GEOMAlgo compiled, without link to GeomUtils which is a Kernel module of Salome.

OCC version macro

replacing OCC version macro header and code in GEOMAlgo_Gluer.hxx with OCCT official header and macro <Standard_Version.hxx>

//#include <Basics_OCCTVersion.hxx>
#include <Standard_Version.hxx>

#if OCC_VERSION_HEX >= 0x070200

// use OCC_VERSION_HEX instead of OCC_VERSION

Add some extra cmake modules

several cmake modules such as "FindOpenCascade.cmake" added into the cMake folder in this repo

SET(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_LIST_DIR}/cMake)

tool to automatically track salome development

It is a feature in the todo list:

git generate patch after comparison
CI test
