我正在尝试为iOS构建IoTivity，并按照here的说明进行操作，但我不断收到此错误，该错误会终止构建。
service/resource-encapsulation/include/RCSException.h:33:10: fatal error: 'boost/config.hpp'
file not found
#include <boost/config.hpp>
^~~~~~~~~~~~~~~~~~

scons: *** [out/ios/arm64/debug/service/resource-encapsulation/src/common/expiryTimer/src/ExpiryTimerImpl.o] Error 1
scons: building terminated because of errors.
当我查看boost框架时，确实看到了config.hpp文件。有谁知道为什么找不到该文件。
