# SYNOPSIS
|
|
#
|
|
# AX_PATH_LIB_PCRE [(A/NA)]
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# check for pcre lib and set PCRE_LIBS and PCRE_CFLAGS accordingly.
|
|
#
|
|
# also provide --with-pcre option that may point to the $prefix of the
|
|
# pcre installation - the macro will check $pcre/include and $pcre/lib to
|
|
# contain the necessary files.
|
|
#
|
|
# the usual two ACTION-IF-FOUND / ACTION-IF-NOT-FOUND are supported and
|
|
# they can take advantage of the LIBS/CFLAGS additions.
