Add OpenMPI rpath and LD_LIBRARY_PATH export for reliable linking

Browse Source 
- Export OMPI_ROOT/lib64 in LD_LIBRARY_PATH so mpicxx finds its runtime libs
- Add -Wl,-rpath to embed OpenMPI lib64 path in executables for runtime
- Replace hardcoded paths with OMPI_ROOT variable

## OpenBLAS (OpenMP variant) + gfortran runtime

## Memory allocator switch
## 0 (default) : use system default allocator (ptmalloc)
