Research direction
Start with the CMake configuration shown in the issue, especially find_package and target_link_libraries, then reproduce the Ubuntu x86_64 build using GCC 7.4.0, CMake 3.14, and Boost 1.71. Done means the program using boost::program_options links without the reported undefined references.

Description
When building a program that uses boost::program_options a couple of undefined refereneces show up:

...
target_link_libraries(project ${Boost_LIBRARIES})
