You are not only doing cross compiling, additionally you are using a toolchain 
which is not yet supported by cmake, so this has to be added.
I.e. the toolchain has to be recognized, and a Modules/Compiler/Tasking.cmake 
or something like this needs to be added.

Please put this in a new bug in the bug tracker at 
http://public.kitware.com/Bug/my_view_page.php , then we can continue there.
