I'm setting CONFIG_BOOT_SIGNATURE_KEY_FILE while building an application with the nRF SDK 1.3.0 from the command line using west:
I see from the application ninja logs that this is correctly signing the image with the specified key (albeit, it assumes that the key is located in `bootloader/mcuboot`, but I can live with that).
However, the public key baked into the MCUBoot build is incorrectly being extracted from the default MCUBoot key, as we can see from the MCUBoot ninja logs:
It looks like the config variable isn't being correctly passed through to the MCUBoot build.
I've tried adding it to the `SHARED_MULTI_IMAGE_VARIABLES` list from my application CMakeLists.txt:
The variable is now being set in `extra_kconfig_options.conf`, however it is missing quotes so the toolchain is refusing to accept it:
Is this a bug, or am I not setting the right config options here?
