如果出现多个c++模块的名称一样，要怎样解决冲突问题？

[masx200]

这种问题在java当中还挺常见，在c++当中有解决办法吗？

举个栗子，在我们目前的项目中使用了A和B两个Jar包，A包在依赖中依赖了C包，而B包在依赖中也同时依赖了C包，但是A包依赖的C的版本的1.0，B依赖C包的版本是2.0。此时，我们的项目中就出现了1.0.和2.0两个版本的C包，此时Maven会依赖路径最短优先原则，来决定使用哪个版本的Jar包，而另外一个无用的Jar包则未被使用，这就是所谓的依赖冲突

<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.7.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>5.2.0.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.2.0.RELEASE</version>
        </dependency>



    </dependencies>

举个例子,在nodejs当中是这样设定的

{
"resolutions": {
       
        "object-path": "0.11.8",
        "ansi-html": "npm:ansi-html-community",
        "nanoid": "3.3.1",
        "follow-redirects": "1.14.9"
    }
}

有没有办法指定某个模块的文件位置？

有两个模块都是同一个名称leetcode_treenode_cpp.TreeNode,就报错了
