CMake automatically orders libraries so that the dependencies come after. 
Unfortunately, FindBoost has a bug and declares log as depending on 
log_setup, rather than vice versa.

No matter how you order the libraries in target_link_libraries, the order 
between these two will never be correct.

Not sure if this is the problem here though.
