# 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.
