Can't compile the ourproject example

I’ve followed along and installed and successfully compiled and tested the examples but when I try to do the [ Creating your first PicoSystem project ] section I’m getting this error:

– Configuring incomplete, errors occurred!
See also “/home/pi/ourproject/build/CMakeFiles/CMakeOutput.log”.
See also “/home/pi/ourproject/build/CMakeFiles/CMakeError.log”.
pi@raspberrypi:~/ourproject/build $ cmake … -DPICOSYSTEM_DIR=/home/pi/picosystem
PICO_SDK_PATH is /home/pi/pico-sdk
PICO platform is rp2040.
CMake Error at /home/pi/picosystem/libraries/picosystem.cmake:3 (pico_generate_pio_header):
** Unknown CMake command “pico_generate_pio_header”.**
Call Stack (most recent call first):

It happens during: [ cmake … -DPICOSYSTEM_DIR=/home/pi/picosystem ]

Thanks for your help,
