-DSB_CONFIG_BOOT_SIGNATURE_KEY_FILE in comand line causes error due to malformated string

[MTB]

Hello

I would like to sign an image temporarily with west CMake options as described in Enabling a bootloader chain using sysbuild using the comand line:

-DSB_CONFIG_BOOT_SIGNATURE_KEY_FILE=\"priv.pem\"

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

-DSB_CONFIG_BOOT_SIGNATURE_KEY_FILE=\"priv.pem\"

In it's final state I would like to specify an absolute path, where the keyfile is stored. It seems as if I am not able to provide the proper format for the path value "D:\priv.pem".

I applied this also to the example "sysbuild\with_MCUboot" and use the nrf sdk v2.7.0. The result is still a malformat for the string.

setting the absolut path in the sysbuild.conf (SB_CONFIG_BOOT_SIGNATURE_KEY_FILE) compiles without error. I tried a lot of combinations but don't seem to get this to work.Also placing the priv.pm in the west topdir and using the example =\"priv.pem\" os not working.

Any idea what I am doing wrong?
