<![CDATA[to decide static or dynamic]]>Dear friends: I am creating a makefile.
Sometimes I can not execute dynamically and sometimes statically. So I want something like following but I do not know how to check in GNU.

#makefile 
     cc = g++
     CFLAGS= -c -g -Wall -O3 -I. -DUNIX 
     if (glibc-static c library exits in operating system), then 
     CFLAGS1= -O3 -I. -DUNIX -static
   else 
     CFLAGS1= -O3 -I. -DUNIX 
    PROG = myprogram
    OBJS = file1.o file2.o 
    $(cc) $(CFLAGS1) -o   $(PROG) $(OBJS)    
  file1.o: file1.cpp file1.h 
		$(cc) $(CFLAGS) file1.cpp file1.h 
  file2.o: file2.cpp file2.h 
		$(cc) $(CFLAGS) file2.cpp file2.h 
PHONY: clean
clean: 	 
		rm $(OBJS)

I do not know how to check this in GNU make. Can anyone write me the codes for the following macro code for GNU make ?

CFLAGS= -c -g -Wall -O3 -I. -DUNIX
     if (glibc-static c library exits in operating system), then
     CFLAGS1= -O3 -I. -DUNIX -static
else
     CFLAGS1= -O3 -I. -DUNIX

I would be very thankful
