Linking problem in platformio

[teomona98]

Hi, I'm having a strange problem and i don't know what to try.
It seems like there's some symbols being redeclared somewhere, but i can't seem to get a hold of the problem.

If i include the Matter.h header file from main.cpp it works perfectly fine but as soon as i include in from any other header file in the project i get the following errors at linking time:

I've tried to exclude it from every file and as soon as I do that, it links perfectly fine.
Thank's in advance.
