使用cmake Rust crate构建项目时，C++共享库及头文件无法安装到/usr/local/{include,lib}路径的问题求助

大家好，我最近在做一个混合Rust和C++的项目，遇到了安装路径的问题，想请教一下各位。

我的项目里，Rust二进制程序rust-bin需要链接到C共享库子项目cpp-lib，我用了rust的cmake crate作为构建依赖。目前整个项目编译构建都能正常完成，但有个问题：C共享库没有被安装到/usr/local/lib，头文件也没到/usr/local/include，它们都只被安装在了cpp-lib子项目的本地路径里，这不符合我的预期。

下面是我的项目结构、各文件内容以及执行的构建步骤：

麻烦各位帮我看看问题出在哪，怎么才能让C++的库和头文件安装到系统的/usr/local/lib和/usr/local/include路径里呢？
