Cannot see CFLAGS

[Hongliang Wang]

Hello, all.

I built two libraries in two directories (gen and ora) respectively and now are 
building the executable program in "util" directory linked against the previous 
libraries. However, errors arise when compling.

This is my Makefile.am in util
--------------------------------------------------------------------------------
# util/Makefile.am

bin_PROGRAMS = zizzy

zizzy_SOURCES = main.c dictionary.c dictionary.h dump.c dump.h zop.c zop.h 
hl.env

zizzy_LDADD = ../gen/libzizzy.a ../ora/libzizora.a
zizzy_CFLAGS = -Wall -Werror `pkg-config --cflags glib-2.0`
zizzy_LDFLAGS = -ggdb `pkg-config --libs glib-2.0`

INCLUDES = -I..

This is my origin Makefile in util
---------------------------------------------------------------------------------
GEN=../gen
ORA=../ora
ZIZLIB=$(GEN)/libzizzy.a
ZIZORALIB=$(ORA)/libzizora.a

CC=gcc
CFLAGS=-I.. -Wall -Werror `pkg-config --cflags glib-2.0`
LDFLAGS=-ggdb `pkg-config --libs glib-2.0`

zizzy: main.c dictionary.c dump.c xml.c zop.c $(ZIZORALIB) $(ZIZLIB)
        $(CC) $(CFLAGS) $(LDFLAGS) $^ -o $@

So I have  two questions:

1, why cannot I see zizzy_CFLAGS in the output message? I can only find 
zizzy_LDFLAGS.

make[2]: Entering directory `/export/guam/jigsaw/dev/jhwgu/src/jz/util'
gcc  -g -O2   -o zizzy -ggdb `pkg-config --libs glib-2.0` zizzy-main.o 
zizzy-dictionary.o zizzy-dump.o zizzy-zop.o ../gen/libzizzy.a 
../ora/libzizora.a -lm

2, why does the compiler trying to re-compile the library file (gen/libzizzy.a 
ora/libzizora.a), but not to use them directly?

Thanks for answering!
