# 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.
|
|
#
|
|
# It extends the Zephyr-sdk CMake package by providing more flexibility in when
|
|
# the Zephyr SDK is loaded and loads additional host tools from the Zephyr SDK.
|
|
#
|
|
# The module defines the following variables when used in normal search and load mode:
|
|
# 'ZEPHYR_SDK_INSTALL_DIR'
|
|
# Install location of the Zephyr SDK
|
|
#
|
|
# 'ZEPHYR_TOOLCHAIN_VARIANT'
|
|
# Zephyr toolchain variant to use if not defined already.
|
|
#
|
|
# 'Zephyr-sdk_FOUND'
|
|
# True if the Zephyr SDK was found.
|
|
|
|
# - LIST: Will list all available Zephyr SDKs found in the system but not load
|
|
# any Sdk. This can be used to fetch available Zephyr-SDKs before doing
|
|
# an actual load.
|
|
# LIST component will define the following lists:
|
|
# - Zephyr-sdk : Version of a Zephyr-SDK
|
|
# - Zephyr-sdk_DIRS : Install dir of the Zephyr-SDK
|
|
# Each entry in Zephyr-SDK has a corresponding entry in Zephyr-SDK_DIRS.
|
|
# For example:
|
|
# index: Zephyr-sdk: Zephyr-sdk_DIRS:
|
|
# 0 0.15.0 /opt/zephyr-sdk-0.15.0
|
|
# 1 0.16.0 /home/<user>/zephyr-sdk-0.16.0
|
|
#
|
|
|
|
include(extensions)
|
|
|
|
# Set internal variables if set in environment.
