When shawn is compiled with the configuration setting BUILD_SINGLE_LIB=OFF,
as described in https://github.com/ibr-alg/wiselib/wiki/All-in-one---wiselib-and-shawn-installation-and-integration , compilation of wiselib apps for shawn fails with multiple linker errors.
Recompiling shawn with BUILD_SINGLE_LIB=ON and then compiling the application seems to circumvent the problem.
