Godot loads C++ libraries through GDExtension and godot-cpp

The guide covers using GDExtension, godot-cpp, and Conan to build native C++ libraries for Godot across platforms, demonstrating flecs with 100,000 simulated particles. The build and binding details can help engineers reuse native libraries in cross-platform projects.

What: Godot’s GDExtension lets games use C and C++ libraries through extensions loaded into an unmodified engine build.
How: The official godot-cpp bindings wrap GDExtension’s C interface; the example uses flecs to simulate particles in a Godot scene.
Why it matters: Native-library builds must match the Godot version and be compiled for each shipping platform.

GDExtension lets Godot load a shared library at runtime. Sketched from the article's own text.
