Can't build RustDesk - Android - rust

Question

I tried to build RustDesk project following documentation at documentation - android build
After executing:
VCPKG_ROOT=/opt/vcpkg ANDROID_NDK_HOME=/opt/android-ndk-r22b flutter/ndk_arm64.sh
I cp-ed vcpkg and android-ndk-r22b from home to /opt to make sure that path is right
I'm getting this one error message:

And to be honest I don't know how to get rid of it, I already tried to understand what is wrong from code-side but I can only find this section in build.rs:
fn install_oboe() {
let target_os = std::env::var("CARGO_CFG_TARGET_OS").unwrap();
if target_os != "android" {
return;
}
let mut target_arch = std::env::var("CARGO_CFG_TARGET_ARCH").unwrap();
if target_arch == "x86_64" {
target_arch = "x64".to_owned();
} else if target_arch == "aarch64" {
target_arch = "arm64".to_owned();
} else {
target_arch = "arm".to_owned();
}
let target = format!("{}-android", target_arch);
let vcpkg_root = std::env::var("VCPKG_ROOT").unwrap();
let mut path: std::path::PathBuf = vcpkg_root.into();
path.push("installed");
path.push(target);
println!(
"{}",
format!(
"cargo:rustc-link-search={}",
path.join("lib").to_str().unwrap()
)
);
println!("cargo:rustc-link-lib=oboe");
println!("cargo:rustc-link-lib=c++");
println!("cargo:rustc-link-lib=OpenSLES");
// I always got some strange link error with oboe, so as workaround, put oboe.cc into oboe src: src/common/AudioStreamBuilder.cpp
// also to avoid libc++_shared not found issue, cp ndk's libc++_shared.so to jniLibs, e.g.
// ./flutter_hbb/android/app/src/main/jniLibs/arm64-v8a/libc++_shared.so
// let include = path.join("include");
//cc::Build::new().file("oboe.cc").include(include).compile("oboe_wrapper");
}
But it doesn't look like anything for me
Also here is function that's generating exception:
fn gen_flutter_rust_bridge() {
let llvm_path = match std::env::var("LLVM_HOME") {
Ok(path) => Some(vec![path]),
Err(_) => None,
};
// Tell Cargo that if the given file changes, to rerun this build script.
println!("cargo:rerun-if-changed=src/flutter_ffi.rs");
// settings for fbr_codegen
let opts = lib_flutter_rust_bridge_codegen::Opts {
// Path of input Rust code
rust_input: "src/flutter_ffi.rs".to_string(),
// Path of output generated Dart code
dart_output: "flutter/lib/generated_bridge.dart".to_string(),
// Path of output generated C header
c_output: Some(vec!["flutter/macos/Runner/bridge_generated.h".to_string()]),
// for other options lets use default
llvm_path,
..Default::default()
};
// run fbr_codegen
lib_flutter_rust_bridge_codegen::frb_codegen(opts).unwrap();
}
Where it's last line is the one that throws this error.
lib_flutter_rust_bridge_codegen::frb_codegen(opts).unwrap();
I know this question really specific but documentation and self-investigation does not helping.
