如何在锈菌货物构建脚本上调用批构建器脚本？

项目生锈洋葱需要编译黑腹 C项目。这源于问题onig\_sys v61.1.0，它试图在windows上构建oniguruma。之后，在Visual 2015的windows上，我们需要调用make_win32.bat，而不是cmake来构建oniguruma C项目。

但是，我不知道如何使用cargo构建器来调用make_win32.bat构建脚本。基于构建脚本，我编辑了默认的构建器build.rs，它试图使用cmake而不是make_win32.bat

extern crate pkg_config;
extern crate cmake;

// use std::env;

// fn compile_with_cmake() {
//     use cmake::Config;

//     let static_link = env::var("CARGO_FEATURE_STATIC_ONIG").is_ok();

//     // Builds the project in the directory located in `oniguruma`, installing it
//     // into $OUT_DIR
//     let mut c = Config::new("oniguruma");

//     let dst = if static_link {
//                   c.define("BUILD_SHARED_LIBS", "OFF")
//               } else {
//                   c.define("CMAKE_MACOSX_RPATH", "NO")
//               }
//               .build();

//     let link_type = if static_link {
//         "static"
//     } else {
//         "dylib"
//     };

//     println!("cargo:rustc-link-search=native={}",
//              dst.join("build").display());
//     println!("cargo:rustc-link-lib={}=onig", link_type);
// }

pub fn main() {

    println!("Opening MAIN!!!!!!!!\n\n\n\n");
    use std::process::Command;

    let status = Command::new("D:\\User\\Downloads\\rust-onig\\onig_sys\\oniguruma\\make_win32.bat").status().unwrap_or_else(|e|
    {
        panic!("failed to execute process: {}", e)
    });

    println!("process exited with: {}", status);
    println!("process exited with: {}", status);
    println!("process exited with: {}", status);
    println!("process exited with: {}", status);
    println!("process exited with: {}", status);

    // if let Ok(_) = pkg_config::find_library("oniguruma") {
    //     return;
    // }

    // compile_with_cmake();
}

但是我的构建器脚本没有被调用，因为从未显示消息process exited with：

所显示的内容，我们何时尝试使用cmake构建器可以查看这个问题--这个问题起源于问题onig\_sys v61.1.0

cmake的问题是生成几个Visual Studio项目，这些项目完全不知道如何构建oniguruma。唯一能够有效构建它的解决方案是make_win32.bat，它已经在oniguruma中。此外，我们需要使用make_win32.bat，而不是让cmake生成Visual Studio。

我在-vv中调用了它，正如user1034749注释的那样，它正确地输出并运行了make_win32.bat文件。

我只需在make_win32.bat中放入命令cd D:\rust-onig\src，因为批处理文件在其他文件夹上运行。

更新

生锈洋葱开发人员增加了内置支持，以直接调用nmake，而不是使用batch文件：https://stackoverflow.com/a/42875974/4934640。
