Hi Ben,
I'm a bit of a novice at cross compiling using the Pico SDK and have some errors when I try and run cmake on a MacBook as per your article on the PicoW in MagPi125. The one causing most problems is where the SDK must be picking up a link to your version on GitHub 6 lines before the end of the error list. I havn't found where that is embedded yet. Unfortunately your article doesn't give full details - assumes a lot of past knowledge about using the SDK :

(base) MacBook-Pro:build Tony$ cmake .. -G”NMake Makefiles” -DPICO_BOARD=PICO_W -DWIFI_SSID=secret-deleted -DWIFI_PASSWORD=secret-deleted
CMake Error: Could not create named generator ”NMake
