# FindDeprecated module provides a single location for deprecated CMake build code.
# Whenever CMake code is deprecated it should be moved to this module and
# corresponding COMPONENTS should be created with name identifying the deprecated code.
#
# This makes it easier to maintain deprecated code and cleanup such code when it
# has been deprecated for two releases.
#
# Example:
# CMakeList.txt contains deprecated code, like:
# if(DEPRECATED_VAR)
# deprecated()
# endif()
#
# such code can easily be around for a long time, so therefore such code should
# be moved to this module and can then be loaded as:
# FindDeprecated.cmake
# if(<deprecated_name> IN_LIST Deprecated_FIND_COMPONENTS)
# # This code has been deprecated after Zephyr x.y
# if(DEPRECATED_VAR)
# deprecated()
# endif()
# endif()
#
# and then in the original CMakeLists.txt, this code is inserted instead:
# find_package(Deprecated COMPONENTS <deprecated_name>)
#
# The module defines the following variables:
#
# 'Deprecated_FOUND', 'DEPRECATED_FOUND'
# True if the Deprecated component was found and loaded.
