Windows CMake 上的 Rust 问题

Question

我已经rustup-init.exe在我的 PC（Windows 10 专业版）上安装了 Rust，然后在 Microsoft Visual C++ Build Tools 2017 上安装了 CMake 选项的 Visual C++ 工具。

举个简单的例子，没有问题：

fn main() {
   println!("Hello world!");
}

我执行cargo run命令，结果我得到Hello world!了预期的结果。

但现在我想看看Azul GUI 框架

主文件

extern crate azul;

fn main() {
   println!("Hello world!");
}

Cargo.toml

[package]
name = "my_first_azul_app"
version = "0.1.0"
authors = ["Author"]
edition = "2018"

[dependencies]
azul = { git = "https://github.com/maps4print/azul" }

当我执行cargo run命令时发生错误：

...

如何使用 CMake 和 Rust 解决此问题？我应该指定 CMake 路径吗？

Answer 1

我通过将 CMake bin 添加到 PATH 变量中来解决它。刚刚在最近安装的 Visual Studio Build Tools 目录中搜索cmake.exe文件或CMake文件夹，发现cmake.exe

对我来说是 C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin

这样我就不必单独安装 CMake。

我还在 Visual Studio Build Tools 的安装过程中添加了 Windows 10 SDK 复选框。

现在构建我的项目时没有错误。我希望这可以帮助别人。
