[neon-build]: How to use build options

[ssssota]

Can I use build options?

I checked this example.
And I tried this in windows 10, rustc 1.49.0 and neon 0.7.0.

build.rs

extern crate neon_build;

fn main() {
    neon_build::Setup::options()
        .output_dir("../dist")
        .setup();
}

then

> neon build --release

neon info forcing rebuild for new build settings
neon info running cargo

   Compiling cfg-if v1.0.0
   Compiling smallvec v1.6.1
   Compiling cslice v0.2.0
   Compiling neon-sys v0.7.0
   Compiling hello-project v0.1.0 (D:\Dev\hello-project\native)
   Compiling neon v0.7.0

Sorry, I can't use English well.
And I don't know Rust well.

Thank you.

These build options are only available with the napi backend. Please ensure you are using the napi backend.

@ssssota It's feature flag based. There are some additional details in the "manual steps" section. #444
