I have a code base with a lot of different c source files in different folders. For projects we want to configure a project folder and reference different source folders from that project. I configured this using CMake and it al compiles fine. Also vscode shows me de code file I need for that project. But intellisense is not working.

CMake generates a c_cpp_properties.json file for me, from which I understand I can use to configure intellisense. But how? I have c_cpp_properties.json file with the folling content:

{
  "configurations": [
    {
      "name": "test",
      "compileCommands": "${workspaceFolder}/build/compile_commands.json"
    }
  ],
  "version": 4
}

I have the following folder structure:

• projects/my_app
  • .vscode
    • vscode.code-workspace
    • c_cpp_properties.json
  • build
    • compile_commands.json
  • source
    • app.c
    • app.h
  • CMakeLists.txt
• components
  • component1
    • source
      • component1.c
      • component1.h
  • component2
    • source
      • component2.c
      • component2.h
• my_lib
  • source
    • …
  • CMakeLists.txt

I also have some extra sources which are not visible in the vscode workspace. But are included in de CMakeLists.txt.

I cannot get intellisense to work.

I expected to use intellisense in vscode for my workspace.
