There is a small question

[lipracer]

I don't know if I understand correctly,the following is the structure of my project directory:

.
├── build
├── CMakeLists.txt
├── include
├── lib
├── pyproject.toml
├── README.md
├── src
├── test
├── third_party
└── tools

What I want to discuss is whether the directory of this src is mandatory, and I mean the name. Can this name be configured by users?
