Error when building PY32F002Bx5: py32f0xx_hal.h: No such file or directory

[WesleyAC]

I cloned this repo, changed MCU_TYPE to PY32F002Bx5, changed ARM_TOOLCHAIN to the correct location (a path in /nix/store, since I'm on NixOS), and ran V=1 make, which gave the following error:

I'm not quite sure what should be happening here. That file does exist as Libraries/PY32F0xx_HAL_Driver/Inc/py32f0xx_hal.h, but it's not included in the INCLUDES in the Makefile in the PY32F002Bx5 case, instead including Libraries/PY32F002B_HAL_Driver/Inc, which has the more specific py32f002b_hal.h. I've tried both directions of fixing that: changing py32f0xx_it.c to include the py32f002b_hal.h and changing the INCLUDES to include the py32f0xx_hal.h, both seem to result in this similar error:

Any idea what the fix is here? I feel like I must be missing something obvious...
