# $NetBSD: bsd.makevars.mk,v 1.5 2010/02/24 22:53:34 joerg Exp $

#
|
|
# This Makefile fragment is included by bsd.prefs.mk to set all of
|
|
# the variables saved through MAKEVARS. Typical usage is:
|
|
#
|
|
# .include "../../mk/bsd.prefs.mk"
|
|
#
|
|
# .if !defined(EXPENSIVE_VAR)
|
|
# EXPENSIVE_VAR!= ( ... an expensive computation ... )
|
|
# .endif
|
|
# MAKEVARS+= EXPENSIVE_VAR
|
|
#
|
|
# This causes EXPENSIVE_VAR to be computed, then subsequently stored in
|
|
# the variable cache file. The next time through, EXPENSIVE_VAR is
|
|
# set by bsd.makevars.mk, which avoids running the expensive computation
|
|
# again.
|
|
#
|
|
# The cache files are created as we pass through each phase of the build,
|
|
# and we only include the latest cache file that was created.
