successfully hardcoded the include path for CXX

[EMCP]

I had to hard-code the include path

    let include_path = "/home/emcp/.conan/data/twsapi/10.25.01/stonks/prod/package/2a448472971d7718b4207a1ee198ae4f78f2995d/include";

from my conan-rs installed library.. but is there a better more elegant way to get this wired together with CXX?

build.rs

use std::path::{Path, PathBuf};
use cxx_build::CFG;
use conan::*;

fn main() {
    // requires : sudo apt install libintelrdfpmath-dev
    println!("cargo:rustc-link-lib=bidgcc000");

    let default_conan_profile = "default";

    let command: InstallCommand = InstallCommandBuilder::new()
        .with_profile(&default_conan_profile)
        .build_policy(BuildPolicy::Missing)
        .recipe_path(Path::new("conanfile.txt"))
        .build();

    if let Some(build_info) = command.generate() {
        println!("using conan build info");
        build_info.cargo_emit();

        let twsapi:&BuildDependency = build_info.get_dependency("twsapi").unwrap();

        let twsapi_inc_dir:Vec<&str> = twsapi.get_include_dirs();

        for dir in &twsapi_inc_dir {
            let twsapi_inc_dir_path = Path::new(dir);
            // Add TWSAPI Conan Pkg to Includes
            CFG.exported_header_dirs.extend([twsapi_inc_dir_path]);
        }
    }

    let build_command = BuildCommandBuilder::new()
        .with_recipe_path(PathBuf::from("../../../conanfile.py"))
        .with_build_path(PathBuf::from("../../../build/"))
        .build();

    if let Some(exit_status) = build_command.run() {
       println!("conan build exited with {}", exit_status);
    }

    let include_path = "/home/emcp/.conan/data/twsapi/10.25.01/stonks/prod/package/2a448472971d7718b4207a1ee198ae4f78f2995d/include";

    cxx_build::bridge("src/main.rs")
        .file("src/gettingstarted.cc")
        .include(include_path)
        .flag_if_supported("-std=c++17")
        .compile("twsapi_helloworld");

    println!("cargo:rerun-if-changed=src/main.rs");
    println!("cargo:rerun-if-changed=src/gettingstarted.cc");
    println!("cargo:rerun-if-changed=include/gettingstarted.h");
}
