Weird error when building libmetal

[MarcioOlibra]

I'm trying to add matter over thread to my firmware, but I keep getting this error:

does anyone know what can be causing this and how to fix it?

Hi,

1. Could you share your prj.conf? 
2. Are you able to compile Libmetal before you attempt to add Matter over Thread?
• I'm trying to add matter over thread to my firmware
Typically we recommend that you go the other way around, i.e start with the Matter template sample and then add your firmware to this application. Are you seeing the same compilation errors when trying with a Matter sample + libmetal?

Kind regards,
Andreas

My project is very complex and unorthodox, so I've created a sample with a lot of stuff removed to be able to share it:

https://github.com/marciogranzotto/nrf-proj-issue-sample

I'm not seeing the same compilation errors when trying to build the matter samples, but since I'm using a custom CMakeLists.txt, and not using west, only cmake and ninja, idk if this could be the issue.

[MarcioOlibra]

I've found the issue... My CMakeLists had this on it:

set(CMAKE_INCLUDE_CURRENT_DIR ON)

which was adding some include paths that were causing this error.
