Depends on what all features in mpiexec you are using.  Typically shipping the contents of the bin and lib directories in your install path should be sufficient, but it assumes that your customers have the same dependency libraries as you (e.g., libc).

Alternatively, you could ask them to do an "apt-get/port/brew/yum install" of mpich on their platform.  It'll either automatically build mpich on their machine or download binaries.
