[Dune] gmsh mesh loading using dune-uggrid

[Stary, Tomas]

Hi,

Thanks, the updating of the dune-grit repository has been helpful.  I
have been able to compile the code including the required header
files.

I am now trying to initialise the uggrid with the following code:

      typedef Dune::UGGrid<dim> GRID;
      GRID grid;

During the compilation I get a linking error:

CMakeFiles/dune-poroelastic.dir/dune-poroelastic.cc.o: In function `main':
/home/tom/Work/dune/dune-poroelastic/src/dune-poroelastic.cc:34: undefined reference to `Dune::UGGrid<3>::UGGrid()'
/home/tom/Work/dune/dune-poroelastic/src/dune-poroelastic.cc:34: undefined reference to `Dune::UGGrid<3>::~UGGrid()'
collect2: error: ld returned 1 exit status

Is there any other way of initialising the UGGrid?

Thank you,

Tomas
