I have been trying to figure out a good directory structure that is maintainable for large C++ projects. During my search I came across this resource here link. If I loosely follow the structure stated in that document, it seems I get something similar to the following
.
├── CMakeLists.txt
├── build
│ ├── Executable-OutputA
│ └── Library-OutputA
├── cmake
│ └── *.cmake
├── docs
├── include
│ └── *.h
├── lib
│ ├── LibraryA
│ │ ├── *.cpp
│ │ └── *.h
│ └── LibraryB
│ ├── *.cpp
│ └── *.h
├── src
│ ├── ExecutableA
│ │ ├── *.cpp
│ │ └── *.h
│ └── ExecutableB
│ ├── *.cpp
│ └── *.h
├── tests
└── third_party
├── External-ProjectA
└── External-ProjectB
- build: holds the outputted executables and libraries generated by the project
- cmake: holds all the cmake packages that the project may require
- doc: holds documentation files, typically doxygen
- include: holds public headers files (might not be needed, not sure)
- lib: holds all the libraries the user creates with their respective source and header files
- src: holds all the executable projects the user makes with their respective headers and source files
- tests: files to test both the executables and libraries
- third_party: any third party projects, libraries, ect. usually downloaded from online or cloned
I believe this is an appropriate structure for large projects, but I do not have too much experience with projects that produce more than 3 or 4 targets. I want to ask the community for feedback and if they agree with the structure laid out above, or have better suggestions.
Edit: I have not been able to find too many posts detailing multiple target outputs as well as third party dependencies for large projects.
