Installation fails without wml
Not sure whether this is a bug or a feature, but without wml we will try to install non-existent html files:
CMake Error at doc/cmake_install.cmake:41 (FILE):
file INSTALL cannot find
"/home/mblatt/DUNE/dune-grid-howto-2.4.1-rc2/doc/navigation.html".
Call Stack (most recent call first):
cmake_install.cmake:270 (INCLUDE)
make: *** [install] Fehler 1
Problem occured with the release tarballs but this probably also applies to master
