makefile

# Make file for console Find_Orb,  using regular Curses
# Use 'bsdmake' for BSD
# GNU MAKE Makefile for Find_Orb
#
# Usage: make -f [path/]linmake [CLANG=Y] [W32=Y] [W64=Y] [MSWIN=Y] [X=Y] [VT=Y] [tgt]
#
#	where tgt can be any of:
# [all|find_orb|fo|fo_serve|clean|clean_temp|eph2tle|cssfield|neat_xvt]
#
#	'W32'/'W64' = cross-compile for 32- or 64-bit Windows,  using MinGW-w64,
#      on a Linux box
#	'MSWIN' = compile for Windows,  using MinGW and PDCurses,  on a Windows machine
#	'CLANG' = use clang instead of GCC;  Linux only
# 'X' = use PDCurses instead of ncurses
# 'VT' = use PDCurses with VT platform (see github.com/Bill-Gray/PDCurses/vt)
# 'CXX=g++-4.8' = use that version of g++;  helpful when testing older compilers
# None of these: compile using g++ on Linux,  for Linux
#
# 'clean_temp' removes various temporary files made by Find_Orb and friends:
# orbital elements,  covariance matrices,  etc.  'clean' removes these _and_
# the more usual object and executable files.

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