- Migrate NCollection map/sequence/array size APIs from int to size_t; Size() returns size_t, Length() remains the int accessor; int overloads delegate through NbBucketsFromInt() with a negative-input guard.
- Add NCollection_LinearVector: contiguous flat-buffer dynamic array with Standard::Reallocate-based growth for trivial types and move-construction for non-trivial types.
- Rewrite NCollection_DynamicArray on top of LinearVector<T*>; switch to power-of-two block sizing with precomputed shift/mask.
- Rework NCollection_BaseMap iterator with a forward findFirst() helper (no negative-bucket arithmetic); unify ReSize/BeginResize/EndResize on size_t.
- Enable thread-safe fast path in NCollection_IncAllocator via std::shared_mutex + CAS bump allocation on atomic AvailableSize; exclusive lock is taken only for new-block allocation and list reordering.
- Remove NCollection_BasePointerVector (superseded by NCollection_LinearVector).
- Remove NCollection_BaseMap::Statistics (unused).
- Add <cstddef> include in NCollection_Primes.hxx so size_t resolves on clean builds.
- Document iterator invalidation contract on NCollection_LinearVector.
- Unify BRepGraph programmatic mutation behind EditorView: delete BuilderView (2648+552 lines); EditorView (3186+930 lines) and EditorView_Mut.cxx own both structural creation (Add*/Remove*) and field-level RAII-scoped mutation (Mut*()) with automatic OwnGen and SubtreeGen propagation.
- Add BRepGraph_MeshCache and BRepGraph_MeshView: two-tier mesh storage separating algorithm-derived caches from persistent (definition) triangulations; freshness is keyed on FaceDef.OwnGen; cache writes do not mutate the model.
- Document the MeshCache invalidation contract in BRepGraph_MeshCache.hxx (which mutations bump Face.OwnGen and how markRepModified closes the loop for Surface/Triangulation reps).
- Add BRepGraph_RefsIterator (generic flat ref scan with RefTraits dispatch) and BRepGraph_ReverseIterator (typed parent-traversal wrappers over reverse-index vectors).
- Rework RefId entity model: replace inline refs with typed RefId vectors; add OccurrenceRef and Kind::Occurrence=7; BRepGraphInc_WireExplorer now requires a VertexRefLookup.
- Rename layers for consistency: BRepGraph_ParamLayer to BRepGraph_LayerParam, BRepGraph_RegularityLayer to BRepGraph_LayerRegularity; rename BRepGraphInc_Usage to BRepGraphInc_Instance.
- Replace RootNodeIds() with RootProductIds() returning product roots only.
- Update BRepGraph and BRepGraphInc READMEs; fix stale RootNodeIds reference.
- Sweep Size() to Length() renames across ~200 callers in TKG2d, TKG3d, TKMath, TKMesh, TKBO, TKOffset, TKShHealing, TKTopAlgo, TKBRep, TKService, TKV3d, TKOpenGl, TKMeshVS, TKDE*, TKXCAF, TKXSBase, TKLCAF, TKStd, and Draw harness.
- Add GTest coverage for new containers and the BRepGraph overhaul: NCollection_DynamicArray_Test, NCollection_LinearVector_Test, BRepGraph_Fuzz_Test, BRepGraph_Iterator_Test, BRepGraph_LayerIterator_Test, BRepGraph_MeshCache_Test, BRepGraph_MutGuard_Test, BRepGraph_ReplaceVertex_Test, BRepGraph_ReverseIterator_Test, BRepGraph_ScenarioMatrix_Test, BRepGraph_TypedIdDispatch_Test, BRepGraph_WireExplorer_Test.

separator.
In case if function/method has NOT declaration in header,
definition must have related comment in doxygen style:
// Descriptions
// @param

The basic implementation of VCPKG as a beta version.
By default will be disabled.

The current version do not support whole list of 3rd-party, only limited.
and VCPKG_ROOT reachable as a CMake or env variable

Removed cotire PCH
Integrated native PCH by CMake with the same BUILD_USE_PCH flag
Added new option to avoid extra files in 'build/include' folder and replace it by symlink
Symlink creates link to the origin file, it has some benefits from debug and build side.
The CMake parameter for symlink is 'BUILD_INCLUDE_SYMLINK'
Moved ExpToCasExe and its DLL to new module - DETools
Created new module - DETools to keep tools to DE
Changed definition of main of ExpToCasExe to not const parameter

Make C++ standard to be enable from cmake settings:
User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD.
For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available.
To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1.
Available next standard items:
C++11
C++14
C++17
C++20
C++23
This issue consists from several steps to achive main goal:
1) Configuratiuon, CMake - allow selecting C++ standard.
2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD).
3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!)
4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation.
5) Update CMAKE requirements in documentation.
6) Set C++11 standard for several projects.
Integration of ExpToCas tool ported to modern state of OCCT:
- new package Express and toolkit TKExpress for EXPRESS data structures and OCCT class generator
- executable ExpToCasExe including lax/yacc parsers, for parsing a Part 21 file and generating classes
Formatting added files from package Express following OCCT Coding Rules
Changes for correspondence generated files to OCCT Code Rules.
Add generation hxx files with declaration of arrays.
If field is a HArray1 method for get length of array and method for get element of array by its index are generated.
Changes for generation parser from Lex and YACC files.
Update description file ReadMe.md
Added option BUILD_SOVERSION_NUMBERS to manage SOVERSION length.
Default option value is set to 2 (major.minor) instead of previously used 1 (major),
excluding Android/Emscripten/Windows platforms that use 0 by default.
