Because the linker fails to find the serialization
library, which I explicitly maintain out of reach
from the IDE.

Maybe the following:

#include <boost/serialization/nvp.hpp>
// rest of serialization headers which must not trigger autolink
#include <...>

int some_function_already present_in_serialization()
{
}

int main(){}

So, if autolink kicks in, the linker will complain about
a duplicate symbol.
