Comment (by renficiaud):

 I have the same problem. I use program_option through cmake, using the
 following define:
   BOOST_ALL_NO_LIB

 since I do not want autolink feature.

 The two variables mentioned in this thread are not found at link time
 unless I define explicitely
   BOOST_ALL_DYN_LINK

 I do not have this problem with boost.system, boost.thread, boost.test and
 boost.chrono for instance. Looking at the config.h file, every define look
 fine (boost.program_options and boost.system).
 It looks like an incoherence in cmake find_boost module: the link is
 against the dynamic variants if Boost_USE_STATIC_LIBS is set to OFF, but
 the BOOST_ALL_DYN_LINK is not defined in Boost and should be defined
 manually.
