[How To] Install HElib on macOS

HElib is an open-source (Apache License v2.0) software library that implements homomorphic encryption (HE). Currently, available schemes are the implementations of the Brakerski-Gentry-Vaikuntanathan (BGV) scheme and the Approximate Number scheme of Cheon-Kim-Kim-Song (CKKS), along with many optimizations to make homomorphic evaluation runs faster, focusing mostly on effective use of the Smart-Vercauteren ciphertext packing techniques and the Gentry-Halevi-Smart optimizations. To install HElib on macOS, follow these steps:

• brew update && brew upgrade && brew autoremove && brew cleanup
  
  
• cd Downloads/
  
  
• git clone https://github.com/homenc/HElib.git

CMake Warning at CMakeLists.txt:264 (message):

  CAUTION: Package build should not be installed globally as it will

  potentially override dependencies.

CMake Warning (dev) at /usr/local/Cellar/cmake/3.24.2/share/cmake/Modules/ExternalProject.cmake:3074 (message):

  The DOWNLOAD_EXTRACT_TIMESTAMP option was not given and policy CMP0135 is

  not set.  The policy's OLD behavior will be used.  When using a URL

  download, the timestamps of extracted files should preferably be that of

  the time of extraction, otherwise code that depends on the extracted

  contents might not be rebuilt if the URL changes.  The OLD behavior

  preserves the timestamps from the archive instead, but this is usually not

  what you want.  Update your project to the NEW behavior or specify the

  DOWNLOAD_EXTRACT_TIMESTAMP option with a value of true to avoid this

  robustness issue.
