I am trying to build this project: https://github.com/sekigon-gonnoc/Pico-PIO-USB

Unfortunately, I am not able to build it. I am on Ubuntu 20 and I have the pico sdk downloaded.

After the cmake command, i get this:

"CMake Error at CMakeLists.txt:11 (add_executable): Cannot find source file: /home/user/pico/pico-sdk/lib/tinyusb/src/portable/raspberrypi/pio_usb/dcd_pio_usb.c"

I then: cd'ed into /pico/pico-sdk and

git submodule update --init --recursive

Which seemed to install a lot of files. However, when i tried building, I got the same error:

 /home/user/pico/pico-sdk/lib/tinyusb/src/portable/raspberrypi/pio_usb/dcd_pio_usb.c

I looked up the directories and I do not have that directory. Inside this directory:

/home/user/pico/pico-sdk/lib/tinyusb/src/portable/raspberrypi/

There is only an rp2040 directory and there is not a pio_usb directory.

So what can i do in order to be able to build this?
