* include_guard requires GLOBAL as family.cmake is included in multiple non child places
* the following recently added check is suprfluous (family_configure_host_example for rp2040 should do this already),
and breaks if pico_pio_usb is not avaialble, so i have removed
# Add pico-pio-usb for rp2040 since user can choose to run on bit-banging host
if(FAMILY STREQUAL "rp2040")
family_add_pico_pio_usb(${PROJECT})
endif()
* added new familt_example_missing_dependency functino to print missing dependency warning, so
pico-examples can override it to be less in your face, and also more contextual to pico-examples
- Examples should be CMake buildable from their own subdirectory; such a build will error out based on
matching .skip.MCU_xxx or a mismatched .only.MCU_
- It should be possible to build from a higher level and use .skip.MCU_ and .only.MCU_ to filter which
examples get built
- The intention is for the CMakeLists.txts in the examples to be non family specific and without MCU based IFs. I have
started this work, but am not really sure the state of the esp32 stuff; in any case the plan is to have
everything encapsulated in the FAMILY/family.cmake
- pico_examples now just includes examples/device/CMakeLists.txt and examples/host/CMakeLists.txt directly, as they
also build correctly when included from there.
Note that .skip.MCU_ for esp32 in the directories it wasn't previously avaiable has not been added, as the .skip is common to the regular Makefile builds also. It isn't clear whether these examples should build for esp32, but if not .skip should be added.
