I have a problem with linking and calling my custom library to opencv library, anyone can help me pleasee?

This my linking code :

$(TARGET): custom.a $(OBJECTS)
   g++ -o main main.o  `pkg-config  --cflags opencv` ../../../lib/custom.a -o `pkg-config --libs opencv`
   chmod 755 $(TARGET)

This error :

make
