[Dune] CMake define ALBERTA_DIM

[Agnese, Marco]

Hi,
I am trying to use CMAKE to compile my projects and so far I have 2 issues. 
With autotools, I was defining ALBERTA_DIM variable in the Makefile.am. With CMake I have added 

add_definitions(-DALBERTA_DIM=2)

into the CMakeList.txt but it doesn't work. Indeed, it seems that the preprocessor variable ALBERTA_DIM is still not defined. What is the CMake way to set this variable which is necessary for ALBERTA?

Another issue which I have is that linking ZOLTAN doesn't work. Following the wiki, I have added 
 
-DCMAKE_PREFIX_PATH=\"$ZOLTAN_DIR\" 

into the CMAKE_FLAGS in my option file but dune-alugrid doesn't find zoltan. Is it a bug inside dune-alugrid or inside some other modules or do I have to add something different in my option file (I did the same with Metis, UMFPACK,... and everything was fine)?

Thank you very much,
cheers,
Marco.
