ceres-solver-sys

Low-level unsafe Rust bindings for Ceres Solver

Currently, we bind C API only using bindgen. The minimal tested version of Ceres Solver is 2.0

Cargo feature flags

• v2_1 wraps Ceres Solver 2.1 API, which added CUDA support
• system (default) links a system copy of the Ceres Solver library. By default, it would be a synamic library, but you can tweak it with pkg-config
• source (optional) overrides system and links a static library file built by ceres-solver-src crate, it is also applies v2_1 feature flag, because ceres-solver-src crate builds Ceres Solver 2.2 from source

system feature requires pkg-config system dependency, while source requires ceres-solver-src build dependencies such as CMake and C++17 compatible compiler.
