# This script installs EvtGen with all external dependencies.
# The variable INSTALL_PREFIX specifies the installation location.
# The variable VERSION specifies the tag of EvtGen you want to use.
# The list of available tags can be found by either going to the url
# https://phab.hepforge.org/source/evtgen/tags/master
# or issuing the command (without the need to clone the git repository)
# git ls-remote --tags http://phab.hepforge.org/source/evtgen.git | cut -d '/' -f3
# The recommended versions of the external dependencies are given below.
# Later versions should be OK as well, assuming their C++ interfaces do not change.
# HepMC (either HepMC2 or HepMC3, the latter is recommended) is mandatory.
# Note that some earlier EvtGen versions will not be compatible with all
# external dependency versions given below, owing to C++ interface differences;
# see the specific tagged version of the EvtGen/README file for guidance.
# It is also not possible to compile Tauola++ on macOS at present, unless you
# are building on a volume with a case sensitive file system, so this is
# disabled by default.
# To obtain this script use the "Download File" option on the right of the webpage:
# https://phab.hepforge.org/source/evtgen/browse/master/setupEvtGen.sh?view=raw
