Library linkage in makefile using gfortran

I have a fortran code (pardiso_1.f) and it needs some libraries (BLAS, lapack and Pardiso libraries) to be compiled. When I try to compile it, I link libraries before compilation and I write this line in linux terminal:

gfortran pardiso_1.f  -L/home/behnam/Pardiso -lpardiso412-GNU450-X86-64 -L/usr/lib -lblas -llapack -fopenmp

and it works perfectly.

However I have to run the code using makefile. I am so new in writing makefiles and I do not know how to do the linkage. I have written this makefile. could anyone help me to find out what is wrong with that?

FC = gfortran
OPT = -O2
PROGRAMS = pardiso_1

all: $(PROGRAMS)
FFLAGS = -fopenmp

#### BLAS, LAPACK and PTHREAD libraries
LBLAS = /usr/lib/

###location of pardiso file
LIBMKL = /home/behnam/PS2/

#### Series of libraries
LIBRARIES= -llapack -lblas -lpthread -lm -lpardiso412-GNU430-X86-64

PATHFC = /usr/bin/

nlace: ${PATHFC}${FC} ${OPT} ${FFLAGS} -I${PROGRAMS} -o nlace.exe \
         -L${LIBMKL} -lpardiso412-GNU430-X86-64\
         -L${LBLAS} ${LIBRARIES}


clean:
    rm -f *.o *.exe fort.* *~ *.mod

veryclean: clean
    rm -f *~ $(PROGRAMS)

The errors are:

Your rule for PROGRAMS does not contain a recipe that includes the library calls. I presume you want something like your nlace rule, but right now, make is not calling any of your -L switches as part of its operation.

Your makefile does not contain the -L/home/behnam/Pardiso part of your command line.
