makefile

# GNU MAKE Makefile for artsat code and utilities
#
# Usage: make [W64=Y] [W32=Y] [MSWIN=Y] [tgt]
#
#	where tgt can be any of:
# [all|get_high|mergetle|obs_tes2|...]
#
# ...see below for complete list.  Note that you have to 'make tle_date' and/or
# 'make tle_date.cgi' separately;  they have a dependency on the 'lunar'
# library (also on my GitHub site).
#
#	'W64'/'W32' = cross-compile for 64- or 32-bit Windows,  using MinGW,
#     on a Linux box
#	'MSWIN' = compile for Windows,  using MinGW and PDCurses,  on a Windows machine
#	'CC=clang' or 'CC=g++-4.8' = use clang or older GCC
#    (I've used gmake CLANG=Y on PC-BSD;  probably works on OS/X too)
# None of these: compile using default g++ on Linux,  for Linux
#

# As CC is an implicit variable, a simple CC?=g++ doesn't work.
# We have to use this trick from https://stackoverflow.com/a/42958970
