Building Matter light-switch-app CMake error

[MurielleH]

I'm trying to build the light-switch-app from Matter but I get following errors

I have already tried to reinstall the sdk (I use v2.8.0) and build it just like that without touching anything, but even then I get this. 

He says he cannot find certain files but they do exist and they are there, but what am I missing? 

Matter exists and he sees zephyr...

Can anyone help me with this?

Hi,

I assume you've installed your SDK and toolchain manually, but could you show me the contents of the v2.8.0 folder? 

Could you also verify if you're using the project chip version of the sample, or the light switch sample from v2.8.0/nrf/samples/matter?

Could you verify if you're using the nRF52840DK, or a custom board?

Kind regards,
Andreas
