libmetis files error!

[mohamedalysayed]

I noticed that when compiling the code on a different Linux architecture, it gives an error when reading libmetis.a file because it should be compiled locally and separately. For this sake, I suggest including libmetis in the "makefile_explicit_dependencies" file in order for the metis library to get compiled from scratch regardless of the hosting architecture (and then we would have libmetis.a file compatible with any hosting Linux machine).
