problem linking with metis libraries with c++

I am a novice when it comes to using and administering linux. In grad school, I had tech support who could help me out, but now I am at a place where I have to figure things out for myself.

I am trying to use a library of functions known as metis-4.0 found at Obtaining METIS | Karypis Lab. I have no problem extracting the tar.gz file and it is all in a directory called metis-4.0, which I put in usr/local/lib/. I followed the instructions to compile and make the library given in the directory and it creates the library libmetis.a in the directory /usr/local/lib/metis-4.0/.

I am using g++ to compile, and everything is compiling correctly, but when I try to link everything together, it doesn’t recognize functions that are supposed to be defined in the library libmetis.a. All of the .o files (for the library) and .h files are in the directory /usr/local/lib/metis-4.0/Lib/

My compilation looks like:

g++ -O2 -I/usr/local/lib/metis-4.0/Lib -c partition.cpp
g++ -O2 -I/usr/local/lib/metis-4.0/Lib -c cuthill-mckee.cpp
g++ -I/usr/local/lib/metis-4.0/Lib -L/usr/local/lib/metis-4.0/Lib -o partition partition.o cuthill-mckee.o -lm -L/usr/local/lib/metis-4.0/libmetis.a
partition.o: In function main': partition.cpp:(.text+0x1c04): undefined reference to METIS_PartGraphKway(int*, int*, int*, int*, int*, int*, int*, int*, int*, int*, int*)’
collect2: ld returned 1 exit status
make: *** [all] Error 1

Can anyone tell me what I am doing wrong?
