# FindHostTools module for locating a set of tools to use on the host for
# Zephyr development.
#
# This module will lookup the following tools for Zephyr development:
# +---------------------------------------------------------------+
# | Tool | Required | Notes: |
# +---------------------------------------------------------------+
# | Generic C-compiler | Yes | Pre-processing of devicetree |
# | Zephyr-sdk | | |
# | gperf | | |
# | openocd | | |
# | bossac | | |
# | imgtool | | |
# +---------------------------------------------------------------+
#
# The module defines the following variables:
#
# 'CMAKE_C_COMPILER'
# Path to C compiler.
# Set to 'CMAKE_C_COMPILER-NOTFOUND' if no C compiler was found.
#
# 'GPERF'
# Path to gperf.
# Set to 'GPERF-NOTFOUND' if gperf was not found.
#
# 'OPENOCD'
# Path to openocd.
# Set to 'OPENOCD-NOTFOUND' if openocd was not found.
#
# 'BOSSAC'
# Path to bossac.
# Set to 'BOSSAC-NOTFOUND' if bossac was not found.
#
# 'IMGTOOL'
# Path to imgtool.
# Set to 'IMGTOOL-NOTFOUND' if imgtool was not found.
#
# 'HostTools_FOUND', 'HOSTTOOLS_FOUND'
# True if all required host tools were found.
