#
# Makefile for ZeroTier One on Linux
#
# This is confirmed to work on distributions newer than CentOS 6 (the
# one used for reference builds) and on 32 and 64 bit x86 and ARM
# machines. It should also work on other 'normal' machines and recent
# distributions. Editing might be required for tiny devices or weird
# distros.
#
# Targets
# one: zerotier-one and symlinks (cli and idtool)
# all: builds 'one'
# selftest: zerotier-selftest
# debug: builds 'one' and 'selftest' with tracing and debug flags
# installer: ZeroTierOneInstaller-... and packages (if possible)
# official: builds 'one' and 'installer'
# clean: removes all built files, objects, other trash
#
# Automagically pick clang or gcc, with preference for clang
# This is only done if we have not overridden these with an environment or CLI variable
