#
# Main Makefile, intended for use on Linux/X11 and compatible platforms
# using GNU Make.
#
# It should guess the paths to the game dependencies on its own, except for
# Boost which is assumed to be installed to the default locations. If you have
# installed Boost to a non-standard location, you will need to override CXXFLAGS
# and LDFLAGS with any applicable -I and -L arguments.
#
# The main options are:
#
# CCACHE The ccache binary that should be used when USE_CCACHE is
# enabled (see below). Defaults to 'ccache'.
# CXX C++ compiler comand line.
# CXXFLAGS Additional C++ compiler options.
# OPTIMIZE If set to 'yes' (default), builds with compiler
# optimizations enabled (-O2). You may alternatively use
# CXXFLAGS to set your own optimization options.
# LDFLAGS Additional linker options.
# USE_CCACHE If set to 'yes' (default), builds using the CCACHE binary
# to run the compiler. If ccache is not installed (i.e.
# found in PATH), this option has no effect.
#
