Error while using Voro++ Package

Hi all.

I've downloaded the Voro++ package and installed it, but I still get the following error while using compute voronoi/atom:

ERROR: Invalid compute style (../modify.cpp:982)

I've followed the steps mentioned in the documentation while installing it, but I'm not sure what the following steps mean:

- to access the Voro++ header files, code compilation should include
the flag '-I/usr/local/include/voro++'.
- to link to the static library, code compilation should include the
flags '-L/usr/local/lib' to tell the linker where to look, and then
'-lvoro++' to link to the library. "

I entered the following command during compilation of liggghts :

make serial -I /usr/local/include/voro++ -L /usr/local/lib -l voro++

Have I done it right?

Any help is much appreciated!
