# Convert Zephyr roots to absolute paths.
#
# This CMake module will convert all relative paths in existing ROOT lists to
# absolute path relative from APPLICATION_SOURCE_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
#
# 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.
