Unofficial bindings to the Gmsh C API (currently v4.4.1).
The bindings are directly generated using `bindgen`.
They're very low-level and you'll likely want them wrapped in a higher-level crate.

You'll need a copy of the Gmsh SDK library (`libgmsh`) to link with.  

If you're getting linker errors when trying to run `cargo test`, try passing 
the Gmsh library location to `LD_LIBRARY_PATH` during the call: 

```shell
LD_LIBRARY_PATH="<libgmsh-path>" cargo test
```

For posterity, the exact `bindgen` call (v0.50.0) was 
```rust
let bindings = bindgen::Builder::default()
                .header("gmsh/api/gmshc.h")
                .generate_comments(true)
                .generate()
                .expect("Unable to generate bindings");

    let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());
    bindings
        .write_to_file(out_path.join("bindings.rs"))
        .expect("Couldn't write bindings!");
```
