# This is a consolidated Makefile for Linux, FreeBSD, Solaris (untested),
# macOS, and Windows (x86_64 and i686).

# Builds for host OS by default; pass TARGET={target_os} to cross-compile,
# where {target_os} is one of linux, freebsd, solaris, macos, win32, or win64.
# Appropriate cross-compiler support must be installed, of course, and build
# options below may need to be changed.

# DETECTED_OS is used both to set certain options for the build
# environment and to determine the default TARGET if it's not
# otherwise specified.
