Oh, I see. I considered it a rethoric question: the application won't
work without recompiling because the (dynamically linked) Boost
libraries won't be found.

Of course, it wouldn't work even if those libraries were found on the
other system, because the libraries are not binary compatible.

There are at least two solutions for the OP:

1. embed Boost into your software. This seems to be a common practice.
Not desirable on embedded systems.

2. write a script that configures your software for the target system.
This isn't an extremely difficult, even without a boost-config script,
except, maybe, for finding the versions of libraries used by Boost
(Python, ICU, etc).
