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() - -macro(CMAKE_RESET_CHECK_STATE) - - set(CMAKE_EXTRA_INCLUDE_FILES) - set(CMAKE_REQUIRED_INCLUDES) - set(CMAKE_REQUIRED_DEFINITIONS) - set(CMAKE_REQUIRED_LIBRARIES) - set(CMAKE_REQUIRED_FLAGS) - set(CMAKE_REQUIRED_QUIET) - -endmacro() - -macro(CMAKE_PUSH_CHECK_STATE) - - if(NOT DEFINED _CMAKE_PUSH_CHECK_STATE_COUNTER) - set(_CMAKE_PUSH_CHECK_STATE_COUNTER 0) - endif() - - math(EXPR _CMAKE_PUSH_CHECK_STATE_COUNTER "${_CMAKE_PUSH_CHECK_STATE_COUNTER}+1") - - set(_CMAKE_EXTRA_INCLUDE_FILES_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER} ${CMAKE_EXTRA_INCLUDE_FILES}) - set(_CMAKE_REQUIRED_INCLUDES_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER} ${CMAKE_REQUIRED_INCLUDES}) - set(_CMAKE_REQUIRED_DEFINITIONS_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER} ${CMAKE_REQUIRED_DEFINITIONS}) - set(_CMAKE_REQUIRED_LIBRARIES_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER} ${CMAKE_REQUIRED_LIBRARIES}) - set(_CMAKE_REQUIRED_FLAGS_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER} ${CMAKE_REQUIRED_FLAGS}) - set(_CMAKE_REQUIRED_QUIET_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER} ${CMAKE_REQUIRED_QUIET}) - - if (ARGC GREATER 0 AND ARGV0 STREQUAL "RESET") - cmake_reset_check_state() - endif() - -endmacro() - -macro(CMAKE_POP_CHECK_STATE) - -# don't pop more than we pushed - if("${_CMAKE_PUSH_CHECK_STATE_COUNTER}" GREATER "0") - - set(CMAKE_EXTRA_INCLUDE_FILES ${_CMAKE_EXTRA_INCLUDE_FILES_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER}}) - set(CMAKE_REQUIRED_INCLUDES ${_CMAKE_REQUIRED_INCLUDES_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER}}) - set(CMAKE_REQUIRED_DEFINITIONS ${_CMAKE_REQUIRED_DEFINITIONS_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER}}) - set(CMAKE_REQUIRED_LIBRARIES ${_CMAKE_REQUIRED_LIBRARIES_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER}}) - set(CMAKE_REQUIRED_FLAGS ${_CMAKE_REQUIRED_FLAGS_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER}}) - set(CMAKE_REQUIRED_QUIET ${_CMAKE_REQUIRED_QUIET_SAVE_${_CMAKE_PUSH_CHECK_STATE_COUNTER}}) - - math(EXPR _CMAKE_PUSH_CHECK_STATE_COUNTER "${_CMAKE_PUSH_CHECK_STATE_COUNTER}-1") - endif() - -endmacro() |
