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'的方法来做到这一点。唯一的规则就是做最容易维护的事情。您的目录结构可以从您提供的少量信息中查找。

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井井有条，那么您可以随时随地对文件进行随机播放。

它是正确的C ++应用程序结构吗？
