cmake: support list mode in Zephyr-sdk module package
Introduce list mode in Zephyr-sdk module package. The list mode allows to list all Zephyr SDK's found in the system without loading any of them. Signature of the list mode is: > find_package(Zephyr-sdk COMPONENTS LIST) Will print valid Zephyr SDKs and their path, as well as defining the following corresponding CMake lists: - Zephyr-sdk : List of Zephyr SDKs' version - Zephyr-sdk_DIRS : List of Directories with a valid Zephyr SDK. Each entry in Zephyr-sdk corresponds to the same entry index in the Zephyr-sdk_DIRS list. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>

# FindZephyr-sdk module for supporting module search mode of Zephyr SDK.
|

#
|

# It is possible to control the behavior of the Zephyr-SDK package using
|

# COMPONENTS.
|
||||
# The Zephyr-SDK package supports the components:
|
||||
# - LOAD: Load a Zephyr-SDK. This is the default behavior if no COMPONENTS is specified.
|
||||
# Its purpose is to allow the find_package basic signature mode to lookup Zephyr
|
||||
# SDK and based on user / environment settings of selected toolchain decide if
|
||||
# the Zephyr SDK CMake package should be loaded.
