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”的方法可以做到这一点。唯一的规则是做任何让你最容易维护的事情。您的目录结构看起来可以从您提供的少量信息中找到。

如果您发现您正在使用的目录结构让您感到痛苦或使事情难以保持井井有条，您可以随时调整文件。
