I created a directory named FT2Plugin in platforms/unix/plugins, then 
created a file there named config.cmake .
The file contains the following line:
PLUGIN_FIND_LIBRARY(FT2 freetype)

This adds a check for the library and uses it while linking. I built the 
plugin as external and it works on ubuntu 9.04.
