It looks like you install OpenMPI in a directory which path is not automatically searched which running programs. So you need to add the path to its bin and lib directory to your system paths.

For example, if you use Linux and bash shell:

 export PATH=$PATH:/your_path/openmpi/bin
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your_path/openmpi/lib

You can check that the path to bin is set correctly by typing

 which mpicxx

Best regards,
