undefined reference to HAL_ADC #74

Issue template

Additional information

I would like to use micro-ROS to read a value of resistance. On the STM32CubeIDE, program can run smoothly but micro-ROS can not.

Expected behavior

Get an output as resistance value measured via micro-ROS.

Actual behavior

~/firmware/freertos_apps/microros_nucleo_f746zg_extensions/build/main.o: in function `MX_ADC1_Init':
~/firmware/freertos_apps/microros_nucleo_f746zg_extensions/Src/main.c:286: undefined reference to `HAL_ADC_Init'

collect2: error: ld returned 1 exit status
make: *** [Makefile:383: ~/firmware/freertos_apps/microros_nucleo_f746zg_extensions/build/micro-ROS.elf] Error 1

The program can not successfully build due to undefined reference. Also hal_adc file is included and located at the same containing file as others hal files. I did not change any directories stucture in micro-ROS's workspace.

Thanks.

Please integrate micro-ROS with STM32CubeIDE using https://github.com/micro-ROS/micro_ros_stm32cubemx_utils#using-this-package-with-stm32cubeide. Let us know if you have any problems by opening an issue there.
