CMake configure incompatible with Boost CMake config files

[Flamefire]

CMake and Boost are moving to targets. Hence if you want to use e.g. Boost.ProgramOptions you have to target_link_libraries(target PUBLIC Boost::program_options) which always works

However here you only link the executable (and not also the libraries) to the boost libraries and use the (discouraged) include_directories("${Boost_INCLUDE_DIRS}") which is problematic:

• Quoting the value may not expand a list of directories -> Remove the quotes
• It might be empty (e.g. for the Boost CMake config option) -> Empty value added, again: Remove the quotes
• It only works with the legacy FindBoost which doesn't work well going forward -> Use target_link_libraries as suggested above INSTEAD

Bottom line: Do not use functions like include_directories where a target_* function exists. Also use target_link_libraries to declare the dependencies of your targets (the naming is a bit misleading, it is not necessarily "linking" but declaring a dependency to another target which may imply linking or "just" adding header paths)
