# @brief: Makefile for 2HDME 
# @author: Joel Oredsson
# 
# This is a makefile for 2HDME. Modify it to your needs! 
# For installation instructions see the README.
#
# Compiling RGE.cpp takes a long time because of the compiler optimizations of 
# the 2-loop RGEs ( ~10 min on a laptop).
#
# The source code is written in C++11 and uses the packages:
#   GNUPLOT: For simple plotting. (comment relevant lines to disable)
#   gsl: For mathematical functions and solving ODEs.
#   Eigen: For linear algebra.
