# Setup basic settings for a Zephyr project.

|
# Sysbuild is a higher level build system used by Zephyr.
|
|
# Sysbuild allows users to build multiple samples for a given system.
|
|
#
|
|
# For this to work, sysbuild manages other Zephyr CMake build systems by setting
|
|
# dedicated build variables.
|
|
# This CMake modules loads the sysbuild cache variables as target properties on
|
|
# a sysbuild_cache target.
|
|
#
|
|
# This ensures that qoutes and lists are correctly preserved.

# remaining of string into a value that populates the property.
