# FindZephyr-sdk module for supporting module search mode of Zephyr SDK. |
|
# |
|
# 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: |
|
# |
|
# '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. |
|
|
|
# Set internal variables if set in environment. |
