Odin is a lightweight, self-contained C++ feature and platform detection library.
It provides simple macros to conditionally enable functionality based on platform, architecture, compiler, and OS capabilities — with zero dependencies.

• Unified macros for platform and feature detection
• No runtime overhead
• Minimal, header-only design
• Easy integration into existing CMake-based projects

#include <odin/config.h>

#if ODIN_PLATFORM_WINDOWS
    // Windows-specific logic
#elif ODIN_PLATFORM_POSIX
    // POSIX-compliant logic

#if ODIN_FEATURE_PTHREAD
    pthread_mutex_lock(&mutex);
