No, the question is not stupid, because we know the name of the macro is not 
a good one: `CGAL_LINKED_WITH_TBB` tells the compiler that `<tbb.h>` can be 
included. That macro is set by our CMake scripts when TBB is detected. And 
the CMake scripts will also ensure that the produced binaries will be linked 
with libtbb.


Actually, when I said:

... I forgot to say that at link time the third-party libraries (such as 
libgmp.so, libmpfr.so) must be linked with. Otherwise you will have link 
errors.
