I am trying to make the https://github.com/raspberrypi/pico-examples/tree/master pico examples in ubuntu while running cmake, I get following error, when I comment the that line it compiles but not generating output files.
CMake Error at serial/CMakeLists.txt:9 (pico_add_extra_outputs): Unknown CMake command "pico_add_extra_outputs".
I tried commenting the line pico_add_extra_outputs(hello_serial) and example_auto_set_url(hello_serial) then it compiles but not getting the output files for pico.
`add_executable(hello_serial hello_serial.c )
pull in common dependencies
target_link_libraries(hello_serial pico_stdlib)
create map/bin/hex/uf2 file etc.
pico_add_extra_outputs(hello_serial)
add url via pico_set_program_url
example_auto_set_url(hello_serial)`
