# Compile PYLOM
#   Compile with g++ or Intel C++ Compiler
#   Compile with the most aggressive optimization setting (O3)
#   Use the most pedantic compiler settings: must compile with no warnings at all
#
# The user may override any desired internal variable by redefining it via command-line:
#   make CXX=g++ [...]
#   make OPTL=-O2 [...]
#   make FLAGS="-Wall -g" [...]
