When I build PicoMiteWeb, which is a BASIC for PICO PI, I get this warning and some errors from the compiler.

#warning stdio USB was configured along with user use of TinyUSB device mode, but CDC is not enabled

I have no ideas how to solve it and the build errors it may produce.

This is the CMakeList.txt:

In my understanding:

Pico_enable_stdio_usb(PicoMiteWeb 1)
pico_enable_stdio_uart(PicoMiteWeb 0)

it should enable the stdin/out over USB, and this is confirmed by the first part of the warning message:

#warning stdio USB was configured...

It is unclear to me the second part of the warning message about the lack of CDC.

The Errors I'm getting are:

    /home/pi/pico/pico-sdk/src/rp2_common/pico_stdio_usb/stdio_usb_descriptors.c:53:24: error: 'TUD_CONFIG_DESC_LEN' undeclared here (not in a function); did you mean 'TUD_RPI_RESET_DESC_LEN'?
     #define USBD_DESC_LEN (TUD_CONFIG_DESC_LEN + TUD_CDC_DESC_LEN)
                            ^~~~~~~~~~~~~~~~~~~

                                    ^~~~~~~~~~~~~

I found the missing definition in pico-sdk/lib/tinyusb/src/device/usbd.h, however, I have not idea how to force the compiler to include it.
