deal.II 8.2 (new formula)

Added support for deal.II library with numerous dependencies
and options.
sorry, but it is not the case here. Read `.3.6` here https://www.dealii.org/developer/users/cmake.html . If you like we can try adding `-DCMAKE_FIND_FRAMEWORK=LAST -Wno-dev` to make it similar to `std_cmake_args`, but I have not tried compiling that way.
