它是正確的C++應用程序結構？

Question

我有一個問題是這個正確的應用程序結構？我從C++和CMake開始，我想以正確的方式開始。

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

沒有「正確'的方式來做到這一點。唯一的規則就是盡一切可能讓你最容易維護。您的目錄結構看起來是從您提供的少量信息中找到的。

如果您發現您正在使用的目錄結構導致您感到痛苦或難以保持組織性，您可以隨時對文件進行洗牌。
