安装简单加密算术库（SEAL）v2.3.1

Question

我正在尝试在Mac（运行MacOS High Sierra版本10.13.6）上安装Simple Encrypted Arithmetic Library（SEAL）v2.3.1。

我遵循INSTALL.txt中的说明，并且尝试构建SEALExamples时，运行cmake时遇到错误。终端输出如下：

Rachels-MacBook-Pro:SEALExamples rachelplayer$ cmake .
-- SEAL detected (version 2.3.1)
-- SEAL build type: Release
-- SEAL debug mode: OFF
-- SEAL using Microsoft GSL: OFF
-- Configuring done
CMake Error at CMakeLists.txt:8 (add_executable):
Target "sealexamples" links to target "Threads::Threads" but the 
target was not found. Perhaps a find_package() call is missing 
for an IMPORTED target, or an ALIAS target is missing?

请让我知道如何解决？我不确定这是一般错误还是仅仅是我的计算机。谢谢！

Answer 1

这是SEAL / cmake / SEALConfig.cmake.in中的错误。为了快速解决，请将以下内容添加到文件的开头：

include(CMakeFindDependencyMacro)
set(CMAKE_THREAD_PREFER_PTHREAD TRUE)
set(THREADS_PREFER_PTHREAD_FLAG TRUE)
find_dependency(Threads REQUIRED)

然后重新配置，构建和重新安装SEAL并重新构建SEALExamples。
