$ make BOARD=rpi-pico flash test -C tests/periph_gpio
make: Entering directory '/home/maribu/Repos/software/RIOT/tests/periph_gpio'
There are unsatisfied feature requirements: periph_timer
/home/maribu/Repos/software/RIOT/tests/periph_gpio/../../Makefile.include:934: *** You can let the build continue on expected errors by setting CONTINUE_ON_EXPECTED_ERRORS=1 to the command line.  Stop.
make: Leaving directory '/home/maribu/Repos/software/RIOT/tests/periph_gpio'
```
