如何配置`arrayfire-rust`来使用`cargo run`？

Question

我正在关注the arrayfire-rust guide来设置我自己的Rust项目。我可以cargo build，但是当我cargo run时，我会得到意想不到的结果。如果我直接从shell运行程序，我会得到预期的结果。

$cargo run
Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs
 Running `target/debug/xxx`
 There are 0 available backends

$cargo build
Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs

$./target/debug/xxx
There are 2 available backends

main.rs ：

extern crate arrayfire as af;
use af::*;

fn main() {
    println!("There are {:?} available backends", get_backend_count());
}

Cargo.toml

[package]
name = "xxx"
version = "0.1.0"
authors = ["xxx"]

[dependencies]
arrayfire = "3.4.1"

我已经提交an issue with the crate，维护人员正在调查。
