Installation guide needs to be updated for 3.0
The installation guide on the website still states that dunecontrol can be run using ./dune-common/bin/dunecontrol --opts=dumux/debug.opts all
This is only true for 2.X versions. In 3.0 we use ./dune-common/bin/dunecontrol --opts=dumux/cmake.opts all
Also the building a test section would now correspond to
cd build-cmake/test/porousmediumflow/2p/implicit/incompressible
make test_2p_incompressible_box
./test_2p_incompressible_box ```
