[Paraview] static instead of shared lib?

[pratik]

I had built the tensorglyph plugin on my laptop, and it compiled into a 
shared library(.so), but on doing the same thing on the cluster it is 
being compiled as a static library(.a)! How to i make it compile share 
library? I have used the SAME cmake install prefix, that given in the 
install file that comes along with the plugin.
I tried using -shared as the compiler flag yet got static lib. What is 
going on here?
