There was a problem hiding this comment.
picotool is actually not needed as download, the build process will download this by itself if not found on path. Here's an example:
cmake -S $(pwd)/repo -B build_test -DPICO_BOARD=pico -DPICO_PLATFORM=rp2040
-- LOG_LEVEL is DEBUG
<snip>
-- Set USB product: USBSID-Pico v1.0
CMake Warning at /home/loud/Development/pi/pico-sdk/tools/Findpicotool.cmake:30 (message):
No installed picotool with version 2.1.1 found - building from source
It is recommended to build and install picotool separately, or to set
PICOTOOL_FETCH_FROM_GIT_PATH to a common directory for all your SDK
projects
