NCS Project Folder Structure Using CMake

[usmanmehmood55]

I want to build a NCS project with a folder structure that might be something like this

project_folder
|
|
|-- components
|   |
|   |-- adc
|   |   |-- include
|   |   |   | adc.h
|   |   |
|   |   |-- src
|   |   |   | adc.c
|   |   |
|   |   | CMakeLists.txt
|   |
|   |
|   |-- twi
|   |   |-- include
|   |   |   | twi.h
|   |   |
|   |   |-- src
|   |   |   | twi.c
|   |   |
|   |   | CMakeLists.txt
|
|
|-- main
|   | main.c
|   | CMakeLists.txt
|
|
| CMakeLists.txt
| prj.conf
| README.md
| .gitignore

How can I achieve this using CMake? Is there an alternate way of doing this? Right now I'm including all the libraries in the CMakeLists.txt inside the parent directory, which I do not want to do.

Any help would be greatly appreciated.

Hi,

 

You use the add_subdirectory() in your root CMakeLists.txt to point to your other CMakeLists.txt files.

folder_project/CMakeLists.txt should then hold:

...

add_subdirectory(components/adc)
add_subdirectory(components/twi)
add_subdirectory(main)

 

Our sample "modem_shell" does something similar by adding many folders and components within its own src/ catalog.

You can look at that as a reference.

 

Kind regards,

Håkon

Thank you for the quick response. I will try and implement this, it looks very promising. 

EDIT:

It absolutely works, thank you for the help :)
