/*!
\ingroup PkgDrawSurfaceMesh

Open a new window and draw `asm`, an instance of the `CGAL::Surface_mesh` class. The function is blocking, that is the program continues as soon as the user closes the window. This function requires `CGAL_Qt5`, and is only available if the macro `CGAL_USE_BASIC_VIEWER` is defined.
Linking with the cmake target `CGAL::CGAL_Basic_viewer` will link with `CGAL_Qt5` and add the definition `CGAL_USE_BASIC_VIEWER`.
\tparam SM an instance of the `CGAL::Surface_mesh` class.
\param asm the surface mesh to draw.
