Required Environment

• Visual Studio: VS 2026 (preferred) — CMake generator: Visual Studio 18 2026
• Fallback: VS 2022 — CMake generator: Visual Studio 17 2022
• CMake version: >= 3.20.0
• Platform: x64

Quick Build (using CMake Presets)

run:

# 1) Configure (VS 2026 recommended)
cmake --preset vs2026

# 2) Build Debug
cmake --build --preset vs2026-debug

If VS 2026 is not available, use VS 2022:

cmake --preset vs2022
cmake --build --preset vs2022-debug

Notes

• This directory is for build intermediates and outputs only.
• To regenerate, delete this directory and rerun cmake --preset ....
• The root CMakeLists.txt enforces Windows generators: only Visual Studio 18 2026 or Visual Studio 17 2022 are allowed.
