Error: recompile with -fpic when try to install Armadillo

I was trying to install Armadillo in my Ubuntu 14.04.
I run cmake . command in the terminal at the folder where the Armadillo files are located and then run make command. I got the following errors. 

/usr/bin/ld: /usr/local/lib/libsuperlu.a(util.c.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; 
recompile with -fPIC
/usr/local/lib/libsuperlu.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
make[2]: *** [libarmadillo.so.7.800.1] Error 1
make[1]: *** [CMakeFiles/armadillo.dir/all] Error 2
make: *** [all] Error 2

How can I rectify this?

The library at /usr/local/lib/libsuperlu.a on your system was most likely not built with -fPIC and you are presumably trying to build a shared library that uses code from libsuperlu.a. If this is your situation, then the compiler is telling you that the code in libsuperlu.a is not relocatable, but your shared library needs it to be. You will need to build your own libsuperlu.a and ensure that all of its object files are compiled with the -fPIC flag, since the libsuperlu.a you currently have installed in /usr/local/lib won't work for you.
