Thanks for your answers!

The problem is, that boost_program_options is a library which needs to be installed on the target. This isn't done with DEPENDS boost only.

But the answer of Patrick Ohly worked for me. Now my package has a dependency to libboost-program-options1.60.0 in the control file!
