It likely doesn't really solve your problem, but don't use 
include_directories, link_directories but the target_* variants of that. 
Similar don't use Boost_INCLUDE_DIRS, Boost_LIBRARIES, ... but use the 
targets provided. I.e. Boost::log

This will make your code much cleaner, shorter, hence easier to maintain 
and maybe already solves your problem.

Maybe including Boost::log_setup before Boost::log in your 
target_link_libraries solves the problem.

Please try that and if that fails run "make VERBOSE=1" and post the 
relevant linker line.
