INCLUDE(EnableWarnings) IF (APPLE) # We cannot simply CHECK_FUNCTION_EXISTS on macOS because # MACOSX_DEPLOYMENT_TARGET may be set to a version in the past # that doesn't have futimens. Instead we need to enable warnings # as errors, then check for the symbol existing in `sys/stat.h`, # then reset warnings as errors. ENABLE_WARNINGS(error) CHECK_SYMBOL_EXISTS(futimens sys/stat.h HAVE_FUTIMENS) DISABLE_WARNINGS(error) ELSE () CHECK_FUNCTION_EXISTS(futimens HAVE_FUTIMENS) ENDIF ()
