Makefile does not work properly for C program

I've done this Makefile with the following structure:

BIN_FILES = array cliente servidor

CC = gcc


CCGLAGS =   -Wall -g


all: CFLAGS=$(CCGLAGS)
 all: $(BIN_FILES)
.PHONY : all

array.o: array.c array.h
    $(CC) -c -Wall -fPIC array.c

cliente.o: cliente.c array.h
    $(CC) -Wall -c cliente.c

cliente: cliente.o array.h
    $(CC) -Wall -o cliente -ldl -lrt

servidor.o: servidor.c mensajes.h
    $(CC) -Wall -c servidor.c -lrt -lpthread

servidor: servidor.o
    $(CC) -o $@ servidor -lrt -lpthread

clean:
    rm -f $(BIN_FILES) *.o

.SUFFIXES:
.PHONY : clean

But when I try to execute it, it only works the first rule. Then the execution stops. My final objective is to make each rule work, because if I execute each rule separately it works:

gcc -c -Wall -fPIC array.c
gcc -fPIC -shared -o libarray.so array.o -lrt
gcc -Wall -o cliente cliente.c -ldl -lrt
gcc -Wall -o servidor servidor.c -lrt -lpthread

Thanks

Edit: Now I obtain the following error applying @Jens modifications: 

make: *** No rule to make the objective 'array', necesary for 'all'. Stop.

The targets for cliente.o and servidor.o should use -c instead of -o, i.e. you want to compile to object files.

There's also no point in specifying header files as dependencies in targets cliente and servidor. The commands for these only link, but don't compile files.

servidor: servidor.o
    $(CC) -o $@ servidor.o -lrt -lpthread

There's also no point is specifying library options -ldl etc when compiling to object files with -c.

cliente.o: cliente.c array.h
    $(CC) -Wall -c cliente.c
