How to debug build.rs file?

[ZhaoXiangXML]

I'm trying to debug a build.rs script in vscode, I tried with the following config:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "build",
            "cargo": {
                "args": [
                    "build",
                    "-vv"
                ],
                "filter": {
                    "name": "physx-sys",
                    "kind": "lib"
                }
            },
        }
    ]
}

However the breakpoints did not hit.

Cargo is not executed under the debugger. Try this.
