#
# ABOUT
# -----
# 
# To build i2p for use in Swift project!
#
# REQUIREMENTS
# ------------
#
# Cmake and command line tools are necessary for build, Homebrew is not. If already
# have a Cmake then Homebrew may not be required. Homebrew is only to install Cmake.
#
# * Xcode command line tools (CLT) xcode-select --install (or let Homebrew install)
# * Homebrew ( https://brew.sh/ )
# * cmake  brew install cmake  OR  brew cask install cmake ( if you want cmake gui also )
# * make sure path is set to Xcode: xcode-select -print-path ( if set to command line tools then problems )
# ** to set path to xcode do something like: sudo xcode-select -switch /<path to xcode>/Xcode.app
#
# HISTORY
# -------
#
# 2019-12-19: First version with Boost 1.71.0, Openssl 1.0.2t, i2pd 2.29.0

# 2020-02-01: Allow for selection of platforms to build Boost (ios, tvos, macos), DEFAULT: all
# 2020-02-11: Update to Openssl 1.1.1d. Give user option to set Boost Platforms and Openssl targets
