[Dune] [CMake] Set external ALUGrid

[Arya Fallahi]

Hi Christoph,

Thank you for your response.

I have actually checked all these solutions yesterday. I worked on it
foralmost 8 hours and could never get it run. I ended up going back to the
traditional autotools where everything was running safely. I think I can
survive till the time autotools are completely deleted from dune.

Regards,
Arya
