[Cmake] CMake and MPI on Sun

[William A. Hoffman]

The MPI on the sun may require more than one library.

First you may need to find the symbols:

nm /usr/pack/mpich-1.2.5-mo/sun4u-sun-solaris2.8/lib/*.a | grep xdr_array  

Then in the advanced option for cmake, set MPI_EXTRA_LIBRARY to the
library or libraries you need.   The problem with MPI is there are lots
of different versions that have different libraries.
