Expert guide for integrating third-party C/C++ libraries into Unreal Engine 5.x projects and plugins. Covers static linking, dynamic linking (DLL/SO/dylib), Build.cs configuration, ModuleType.External, delay loading, runtime dependency staging, wrapping patterns, cross-platform considerations (Windows/macOS/Linux), ABI compatibility, RTTI/exceptions, header inclusion with THIRD_PARTY_INCLUDES_START/END, and common pitfalls. Use when the user asks about adding external libraries, third-party code, linking .lib/.a/.dll/.so/.dylib files, Build.cs PublicAdditionalLibraries, PublicDelayLoadDLLs, RuntimeDependencies, ModuleType.External, wrapping a C++ library for UE, FPlatformProcess::GetDllHandle, cross-compiling libraries for UE on Linux, or troubleshooting linker errors / DLL load failures with third-party code.
