I am using NCS v2.9.1 and trying to enable a bootloader chain with NSIB and MCUboot. The regular setup works fine, however if I try to enable the minimal configuration, I get a build errors (for NSIB) and CMake error (for MCUboot). I am using the instructions on this page of the docs.
The issue can be reproduced using the hello_world sample and using the following command:

west build -b nrf52840dk/nrf52840 zephyr/samples/hello_world -- \
-DSB_CONFIG_SECURE_BOOT_APPCORE=y \
-Db0_FILE_SUFFIX=minimal
This results in the following error:
