Create iso image using the wic script in the isar package

Hi,

I was able to create a custom image in wic format with isar and now trying 
to create a bootable iso image. I found the wic script in the isar package 
and attempted to run with the command:
wic create mkhybridiso -e isar-image-base

However I got the following error:
INFO: Building wic-tools...

Loading cache: 100% 
|#######################################################################################################################################################| 
Time: 0:00:00

    return hlp.invoke_subcommand(args, parser, hlp.wic_help_usage,

    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['bitbake', 'wic-tools']' returned 
non-zero exit status 1.

Is there any suggestion on how to resolve this issue? 

Thanks!

Hello John,

As you can see in generate_wic_image() task code, Isar supposed to call WIC
script inside special chroot environment. You can take this task as a 
reference
to create you own task with additional imager_run call of custom WIC 
command.

P.S.
WIC script was brought from OpenEmbedded which really has wic-tools.bb 
recipe.
Isar don't have such a recipe, so this fallback is not working.
