nrf52840 mesh build project. log: boards.h: No such file or directory

Currently I want to build the light_switch examples from the nrf5_SDK_for_Mesh_v4.2.0  on my nrf52840 dev board but this gives the following error "boards.h: No such file or directory". I have placed the nRF5_SDK_17.0.0_9d13099 in the same folder as the nrf5_SDK_for_Mesh_v4.2.0, but I still keep the same issue.

What am I missing?

My folder structure should then be such:

  • <common folder>
    • nRF5_SDK_17.0.0_9d13099
      • components
      • config
      • documentation
      • examples
      • ...
    • nrf5_SDK_for_Mesh_v4.2.0_src
      • bin
      • CMake
      • doc
      • examples
      • ...
