[Cmake] CMake and MPI on Sun

[William A. Hoffman]

My guess is the difference between the Sun and Linux is shared vs. static libraries.
Shared libraries can be linked to other libraries, however static libraries need
dependant libraries listed explicitly.   

Since you may run into a static linked linux system, you may want to do this
instead:

IF(UNIX)
        TARGET_LINK_LIBRARIES(
                MPITest
                socket;nsu;rt
        )
ENDIF(UNIX)
