它是正确的C++应用程序结构？

Question

我有一个问题是这个正确的应用程序结构？我从C++和CMake开始，我想以正确的方式开始。

Root 
|--build 
|--src 
| |-Application 
| | |-------App.cpp 
| | |-------App.h 
| | |-------CMakeLists.txt 
| |-Logger 
| | |--Some files 
| | |--CMakeLists 
| |-CMakeLists.txt 
| |-main.cpp 
|--CMakeLists.txt

没有“正确'的方式来做到这一点。唯一的规则就是尽一切可能让你最容易维护。您的目录结构看起来是从您提供的少量信息中找到的。

如果您发现您正在使用的目录结构导致您感到痛苦或难以保持组织性，您可以随时对文件进行洗牌。
