Build errors while trying to add boost::stacktrace to CMake project - c++

Question

I'm trying to add boost::stacktrace library to my project via CMake. CMake finds all required libs well, but when I call boost::stacktrace::stacktrace() to print stack information into std::cout - it gives me the following error:
undefined reference to 'dladdr'
I've already tried to add the -ldl compile flag to the CMAKE_CXX_FLAGS compile flags to see if it can help, but it doesn't work. I understand that I missed some required packages, but I don't know which. Maybe you could advise me.
Gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04)
Boost version 1.68.0
Here is some code:

Answer 1

Turning my comment into an answer:
Because the dl library is needed by boost::stacktrace (see the Boost requirements), the dl library should be linked after the Boost stacktrace libraries are linked. To ensure this ordering, link the dl library (and perhaps pthread as well) at the end of the target_link_libraries() call instead:
target_link_libraries(${PROJECT_NAME}
PUBLIC ${Boost_STACKTRACE_BASIC_LIBRARY}
PUBLIC ${Boost_STACKTRACE_BACKTRACE_LIBRARY}
PUBLIC ${Boost_STACKTRACE_ADDR2LINE_LIBRARY}
PUBLIC ${Boost_STACKTRACE_NOOP_LIBRARY}
PUBLIC pthread dl
