错误："shared_mutex"不是使用读取器锁定 = std：：shared_lock<std：：shared_mutex> 的"std"的成员;

error: ‘shared_mutex’ is not a member of ‘std’ using ReaderLock = std::shared_lock<std::shared_mutex>;

我正在尝试使用微软海豹库进行同态加密，并按照以下链接中的步骤进行操作 https://github.com/cyberweapons/SEAL/blob/master/INSTALL.txt 当我使用命令 cmake . 终端显示以下结果

-- SEAL detected (version 2.3.1)
-- SEAL build type: Release
-- SEAL debug mode: OFF
-- SEAL using Microsoft GSL: OFF
-- Configuring done
-- Generating done
-- Build files have been written to: /home/ravindra/Desktop/../../MiSEAL/SEAL/SEALExamples

之后，当我给出make命令时，它应该生成一个文件main.cpp.o，而是给出以下错误。

我是 SEAL 库的新手，我也是 C++ 编程的初学者，请有人帮助我解决这个问题。

嗨，我找到了解决方案， 我在CMakeLists中包含以下命令.txt文件继续执行步骤 `

# Below is TFHE START
export TFHE_PREFIX=/usr/local
export CPLUS_INCLUDE_PATH=${TFHE_PREFIX}/include:${CPLUS_INCLUDE_PATH}
export C_INCLUDE_PATH=${TFHE_PREFIX}/include:${C_INCLUDE_PATH}
export LIBRARY_PATH=${TFHE_PREFIX}/lib:${LIBRARY_PATH}
export LD_LIBRARY_PATH=${TFHE_PREFIX}/lib:${LD_LIBRARY_PATH}
# Below is TFHE END
