PX4 Build Error: CMake Error at cmake/px4_add_module.cmake:236 (get_target_property): get_target_property() called with non-existent target "drivers__uavcan"

I want to add a radar distance sensor based on CAN communication. I want to use the driver provided by the src/drivers/uavcan library as the underlying communication driver of CAN. This error message appears when making dependencies. Does anyone know how to solve this error?

src/distance_sensor/radar_can/CMakeLists.txt：

px4_add_module(
	MODULE drivers__distance_sensor__radar_can
	MAIN radar_can
	COMPILE_FLAGS
		-Wno-cast-align # TODO: fix and enable

	INCLUDES
		${PX4_SOURCE_DIR}/src/drivers/uavcan
	SRCS
		radar_can.cpp
		radar_can_main.cpp
	DEPENDS
		px4_work_queue
		drivers_rangefinder
		drivers__uavcan
	)

could it simply be the double underscore?
try: drivers_uavcan
instead of drivers__uavcan

I tried it, still the same error！Because there is a related definition in the uavcan driver：


px4_add_module(
	MODULE drivers__uavcan
	MAIN uavcan
	STACK_MAIN 4096
	COMPILE_FLAGS
		-Wno-format-security # logmessage.hpp
