The optional third argument may be used to add compilation flags to the check (or use ``CMAKE_REQUIRED_FLAGS`` below). The following variables may be set before calling this macro to modify the way the check is run: ``CMAKE_REQUIRED_FLAGS`` string of compile command line flags. ``CMAKE_REQUIRED_DEFINITIONS`` a :ref:`;-list ` of macros to define (-DFOO=bar). ``CMAKE_REQUIRED_INCLUDES`` a :ref:`;-list ` of header search paths to pass to the compiler. ``CMAKE_REQUIRED_LINK_OPTIONS`` .. versionadded:: 3.14 a :ref:`;-list ` of options to add to the link command. ``CMAKE_REQUIRED_LIBRARIES`` a :ref:`;-list ` of libraries to add to the link command. See policy :policy:`CMP0075`. ``CMAKE_REQUIRED_QUIET`` .. versionadded:: 3.1 execute quietly without messages. See modules :module:`CheckIncludeFile` and :module:`CheckIncludeFiles` to check for one or more ``C`` headers. #]=======================================================================] include_guard(GLOBAL) macro(CHECK_INCLUDE_FILE_CXX INCLUDE VARIABLE) if(NOT DEFINED "${VARIABLE}" OR "x${${VARIABLE}}" STREQUAL "x${VARIABLE}") if(CMAKE_REQUIRED_INCLUDES) set(CHECK_INCLUDE_FILE_CXX_INCLUDE_DIRS "-DINCLUDE_DIRECTORIES=${CMAKE_REQUIRED_INCLUDES}") else() set(CHECK_INCLUDE_FILE_CXX_INCLUDE_DIRS) endif() set(MACRO_CHECK_INCLUDE_FILE_FLAGS ${CMAKE_REQUIRED_FLAGS}) set(CHECK_INCLUDE_FILE_VAR ${INCLUDE}) configure_file(${CMAKE_ROOT}/Modules/CheckIncludeFile.cxx.in ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeTmp/CheckIncludeFile.cxx) if(NOT CMAKE_REQUIRED_QUIET) message(CHECK_START "Looking for C++ include ${INCLUDE}") endif() if(${ARGC} EQUAL 3) set(CMAKE_CXX_FLAGS_SAVE ${CMAKE_CXX_FLAGS}) string(APPEND CMAKE_CXX_FLAGS " ${ARGV2}") endif() set(_CIF_LINK_OPTIONS) if(CMAKE_REQUIRED_LINK_OPTIONS) set(_CIF_LINK_OPTIONS LINK_OPTIONS ${CMAKE_REQUIRED_LINK_OPTIONS}) endif() set(_CIF_LINK_LIBRARIES "") if(CMAKE_REQUIRED_LIBRARIES) cmake_policy(GET CMP0075 _CIF_CMP0075 PARENT_SCOPE # undocumented, do not use outside of CMake ) if("x${_CIF_CMP0075}x" STREQUAL "xNEWx") set(_CIF_LINK_LIBRARIES LINK_LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}) elseif("x${_CIF_CMP0075}x" STREQUAL "xOLDx") elseif(NOT _CIF_CMP0075_WARNED) set(_CIF_CMP0075_WARNED 1) message(AUTHOR_WARNING "Policy CMP0075 is not set: Include file check macros honor CMAKE_REQUIRED_LIBRARIES.
