It tends to generate a lot of output around:

CMake Warning at /usr/share/cmake/Modules/FindBoost.cmake:1204 (message):
  New Boost version may have incorrect or missing dependencies and imported
  targets


Specifically for trying to build FreeCAD it KIND OF finds the libraries:

-- Found Boost: /usr/include (found suitable version "1.75.0", minimum required is "1.55") found components: filesystem program_options regex system thread chrono date_time atomic

But then later:

CMake Warning at /usr/share/cmake/Modules/FindBoost.cmake:1204 (message):

And then freecad (a fork testing vtk9 compatibility) fails with:

/usr/bin/ld: ../../lib/libFreeCADApp.so: undefined reference to `boost::match_results<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > >::maybe_assign(boost::match_results<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > > const&)'

...

But when FreeCADApp is actually linking only /usr/lib64/libboost_serialization.so is linked against.

WTH!?!?! What a mess.
