x86_x64

Is your feature request related to a problem? Please describe.
The build script currently lacks the ability to automatically build and install the OpenMPI library.
Furthermore, the support for the OpenMPI library in the setup file generation is currently not quite robust and well developed.

Describe the solution you'd like
The kernel build script should accept the name of the MPI library to be used for building the ParaMonte library. It must then be able to check if the requested library exists on the system and if not be able to automatically download and install the library on the system and use the requested MPI library to build ParaMonte and run examples and tests using the requested library.

Describe alternatives you've considered if any
The current solution requires a manual installation of the OpenMPI library which is not optimal.
