# SYNOPSIS
|
|
#
|
|
# AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro sets VARNAME to the expansion of the DIR variable, taking
|
|
# care of fixing up ${prefix} and such.
|
|
#
|
|
# VARNAME is then offered as both an output variable and a C preprocessor
|
|
# symbol.
|
|
#
|
|
# Example:
|
|
#
|
|
# AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.])
|
