BUG: GET_DIRECTORY_PROPERTY(INCLUDE_DIRECTORIES|LINK_DIRECTORIES) wasn't

working, for both the result was always empty, since
cmMakefile::GetProperty() recognized it as a special property, constructed a
correct return value and called cmMakefile::SetProperty() with this list of
directories, which then didn't actually set the property, but applied it to
the internal vector of include/link directories. The following
getPropertyValue in cmMakefile::GetProperty() then still didn't find it and
returned nothing. Now for all special property the static string output is
used and its content is returned. I'm not sure it is the right way to fix
this problem but at least it seems to work and it fixes the Paraview3 build
