Actual Include paths do not correspond to Include Paths in the settings

[Toin]

Hello, I am trying to add source files in my project, the folder is organized like this : 
- events :
     |  - include :
     |      |  - events :
     |      |      |  - internal :
     |      |      |      |  - Some header files [A]
     |      |      |  - Some other header files [B]
     |  - source :
     |      |  -  .c and .cpp files

I copied the same path list to GCC asm, GCC compiler, G++ compiler :

When compiling i get "include not found" errors, i think it fails when including "folder/header.h" instead of just "header.h", but I am not certain.

I noticed that at the end of the compile command, there is this file mentioned :
"mbed-os/events/source/EventQueue.cpp_includes.args"

This file contains a list of inclusion arguments which look like what I'm including in the project properties, but the "events" folder is missing.
It is being refreshed at every compilation because if i modify it, it goes back to the initial state

I also added a "TEST" folder and added it to the included paths, and it does not appear either

What am I missing to give the compiler the correct paths ?

Thanks in advance

Update : Some cpp files at the root of the project DO get the updated cpp_includes.args, but the source files in "events" do not

For ASCII Art to work, it must be in a mono-spaced font - so use the </> source code button.

Yes, that's always the trouble with relative paths - you have to be sure what it's relative to !

Hence best to stick to just the "header.h" form, and be sure to add the folder to the paths.

[Andrew Neil]

That could also be a result of relative paths ...

Found the problem... 
For some reason, the events folder had specific build settings
I found them by right-click on "events" --> properties, It had an old version of the project include paths
Is there a toggle for folder specific settings ? 
I must have enabled them unknowingly :\
