This option was added by commit v2.8.12~138^2 (Add cmake_reset_check_state() macro, 2013-07-28) but has never worked. Fix the implementation to refer to macro arguments properly (not as normal variables). Fixes: #17048

# CMakePushCheckState
|
|
# -------------------
|
|
#
|
|
#
|
|
#
|
|
# This module defines three macros: CMAKE_PUSH_CHECK_STATE()
|
|
# CMAKE_POP_CHECK_STATE() and CMAKE_RESET_CHECK_STATE() These macros can
|
|
# be used to save, restore and reset (i.e., clear contents) the state of
|
|
# the variables CMAKE_REQUIRED_FLAGS, CMAKE_REQUIRED_DEFINITIONS,
|
|
# CMAKE_REQUIRED_LIBRARIES, CMAKE_REQUIRED_INCLUDES and CMAKE_EXTRA_INCLUDE_FILES
|
|
# used by the various Check-files coming with CMake, like e.g.
|
|
# check_function_exists() etc. The variable contents are pushed on a
|
|
# stack, pushing multiple times is supported. This is useful e.g. when
|
|
# executing such tests in a Find-module, where they have to be set, but
|
|
# after the Find-module has been executed they should have the same
|
|
# value as they had before.
|
|
#
|
|
# CMAKE_PUSH_CHECK_STATE() macro receives optional argument RESET.
|
|
# Whether it's specified, CMAKE_PUSH_CHECK_STATE() will set all
|
|
# CMAKE_REQUIRED_* variables to empty values, same as
|
|
# CMAKE_RESET_CHECK_STATE() call will do.
|
|
#
|
|
# Usage:
|
|
#
|
|
# ::
|
|
#
|
|
# cmake_push_check_state(RESET)
|
|
# set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF)
|
|
# check_function_exists(...)
|
|
# cmake_reset_check_state()
|
|
# set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF)
|
|
# check_function_exists(...)
|
|
# cmake_pop_check_state()
