freebsd-dev/share/mk/src.opts.mk
Warner Losh 22cac7546c Introduce kern.opts.mk to hold all the options for kernel module
builds. Include this in the right places. Make src.opts.mk optional so
that modules can be built outside of the tree in the ports system.

Makefile

# $FreeBSD$
#
# Option file for FreeBSD /usr/src builds.
#
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
# with sensible (usually) defaults.
#
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
# are applicable for that Makefile (typically there are none, but sometimes there
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
# to omit from that make.
#
# Makefiles must include bsd.srcpot.mk before they test the value of any MK_FOO
# variable.
#
# Makefiles may also assume that this file is included by src.opts.mk should it
# need variables defined there prior to the end of the Makefile where
# bsd.{subdir,lib.bin}.mk is traditionally included.
#
# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
# should be added. Old instances should be removed since they were just to
# bridge the gap between FreeBSD 4 and FreeBSD 5.
#
# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
# exception is made for _WITHOUT_SRCONF which turns off this mechanism
# completely inside bsd.*.mk files).
#

# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.

# used at all in bsd.*.mk, but we have to make an exception here if we want
# to allow defaults for some things like clang to vary by target architecture.
