Adds support for sysbuild loading snippets, these can be included by using e.g.: cmake ... -DSB_SNIPPET=blah for sysbuild directly or can be used with an application and sysbuild using -DSNIPPET. Snippets for sysbuild can use SB_EXTRA_CONF_FILE in the snippet file to specify an extra Kconfig fragment for sysbuild Signed-off-by: Jamie McCrae <jamie.mccrae@nordicsemi.no>

# Convert Zephyr roots to absolute paths to be used by sysbuild.
|
|
#
|
|
# This CMake module will convert all relative paths in existing ROOT lists to
|
|
# absolute path relative from APP_DIR.
|
|
#
|
|
# Optional variables:
|
|
# - ARCH_ROOT: CMake list of arch roots containing arch implementations
|
|
# - SOC_ROOT: CMake list of SoC roots containing SoC implementations
|
|
# - BOARD_ROOT: CMake list of board roots containing board and shield implementations
|
|
# - MODULE_EXT_ROOT: CMake list of module external roots containing module glue code
|
|
# - SCA_ROOT: CMake list of SCA roots containing static code analysis integration code
|
|
#
|
|
# If a root is defined it will check the list of paths in the root and convert
|
|
# any relative path to absolute path and update the root list.
|
|
# If a root is undefined it will still be undefined when this module has loaded.
|
|
#
|
|
# Converted paths are placed in the CMake cache so that they are propagated
|
|
# correctly to image builds.
