Linux下编译libnetfilter_queue configure错误：
checking for LIBNFNETLINK... configure: error: Cannot find libnfnetlink >= 0.0.16
出现上面错误是因为未指明PKG-CONFIG搜索libnfnetlink的路径,所以编译libnetfilter_queue必须要加上
PKG_CONFIG=/modules/ips/pkg-config/bin/pkg-config LIBNFNETLINK_CFLAGS=/modules/ips/libnfnetlink/include/libnfnetlink/libnfnetlink.h
LIBNFNETLINK_LIBS=/modules/ips/libnfnetlink/lib
