This is exactly the problem! You cannot mix two TBB libraries (internal
and external in your case, but that doesn't matter) in the link
interface.
Out of curiosity, can you please attach the detailed.log file so that we
can have a look at the full link interface? :-) I am curious where tbb
comes in.
You have to recompile deal.II to use the external TBB library
instead. [1]
Best,
Matthias
[1] I checked - on my systems you minimal example does not show a
problem - nice minimal test case by the way!
