Parallel program wont make

I have moved a parallel program that was working and built in visual studio. I'm using c++ and compiling on the intel compiler. I have to move the project to a linux machine and run it. So I made the following make file.

parallel: main.o Node.o
    icpc -o parallel main.o Node.o

main.o: main.cpp
    icpc -c $(CONFIG) main.cpp

Node.o: Node.cpp
    icpc -c $(CONFIG) Node.cpp

clean:
    rm -f parallel *.o core core.*

CONFIG  = -openmp

but get this output. I can't figure out why it's not recognizing when it works on windows. 

main.cpp:(.text+0x4e): undefined reference to `__kmpc_begin'
main.cpp:(.text+0xa2): undefined reference to `__kmpc_global_thread_num'
main.cpp:(.text+0xb2): undefined reference to `__kmpc_ok_to_fork'
main.cpp:(.text+0xc9): undefined reference to `__kmpc_fork_call'
main.cpp:(.text+0xdb): undefined reference to `__kmpc_serialized_parallel'
main.cpp:(.text+0xfa): undefined reference to `__kmpc_end_serialized_parallel'
main.cpp:(.text+0x106): undefined reference to `__kmpc_ok_to_fork'
""                  ""                         '""             """

Although I don't think it's necessary here is my project.

You are not linking with -openmp; change your second line to 

 icpc $(CONFIG) -o parallel main.o Node.o
