* Retired support for Windows 7 and Windows 8.0

* CMake project updates including support for BUILD_SHARED_LIBS (i.e. DLL vs. static library)

* All enums now use``uint32_t`` as the underlying type rather than``unsigned long`` or``int``.

* WaveFrontReader utililty moved into``DX`` namespace

This package contains DirectXMesh, a shared source library for performing various geometry content processing operations including generating normals and tangent frames, triangle adjacency computations, vertex cache optimization, and meshlet generation.

For a full change history, see[CHANGELOG.md](https://github.com/microsoft/DirectXMesh/blob/main/CHANGELOG.md).

* Starting with the March 2025 release, Windows 7 and Windows 8.0 support has been retired.

* Starting with the June 2020 release, this library makes use of typed enum bitmask flags per the recommendation of the_C++ Standard_ section*17.5.2.1.3 Bitmask types*. This is consistent with Direct3D 12's use of the``DEFINE_ENUM_FLAG_OPERATORS`` macro. This may have*breaking change* impacts to client code:

* You cannot pass the``0`` literal as your flags value. Instead you must make use of the appropriate default enum value:``CNORM_DEFAULT``,``VALIDATE_DEFAULT``, or``MESHLET_DEFAULT``.
