Bth class - 'define CFG_TUD_BTH 1' produces 'undefined reference' error

Hi! Just trying to play with bth class, but when I try to define CFG_TUD_BTH 1 in CMakeLists.txt or tusb_config.h I get:

The goal it to make USB Bluetooth adapter out of the Pico W. Now it is mostly usable by btattach serial USB way under Ubuntu, but trying to utilise USB now. Tried TinyUSB 10.1, 12, 15, 16. No idea what is wrong, event tried to deifdef if CFG_TUD_BTH is somehow ignored, so CFG_TUD_BTH configuration will be always present, but the same error, it is not the issue here I guess.

It required adding lines inside hw\bsp\rp2040\family.cmake:

${TOP}/src/class/bth/bth_device.c
${PICO_TINYUSB_PATH}/src/class/bth/bth_device.c

and here src\CMakeLists.txt:

${CMAKE_CURRENT_FUNCTION_LIST_DIR}/class/bth/bth_device.c

and maybe here src\tinyusb.mk:

src/class/bth/bth_device.c \
