The dynamic library libslepc.so is not found at run time. A solution is to add
the correct path to your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SLEPC_DIR/lib/linux-gnu-cxx-debug
                                                       ^^^^^^^^^^^^^^^^^^^*)

*) might differ if you build with a different compiler or on a different
system etc.

Eventually, the build system should figure this out the same way as with
PETSc, since they are very similar put together.
