Could NOT find MPI_C (missing: MPI_C_LIBRARIES MPI_C_INCLUDE_PATH)

[PerfectWzp]

I run "cmake .." in Multiverso/build/, then it appears below errors.
I have installed openmpi-1.8-1.8.1-5.el6.x86_64 using yum.
then how I solve this MPI_C problem ?

Hi, please make sure that MPI path was under your $(PATH).
