OpenRealm ROS1 Bridge problems - c++

Question

I have some problem following this installation guide https://github.com/laxnpander/OpenREALM_ROS1_Bridge
Before quick start section, the command catkin_make -DCMAKE_BUILD_TYPE=Release does not work.
It is the last step before to use the whole library.
Someone can help me?
Example of the errors:

target was not found. Perhaps a find_package() call is missing for an
IMPORTED target, or an ALIAS target is missing?

I don't have any idea of how to solve it.
Cheers!

You need to make sure the correct boost libraries are actually added to the CMakeLists.txt. That repo does not appear to be set up correctly. In realm_ros/CMakeLists.txt find the line target_link_libraries(...) and add:
${Boost_FILESYSTEM_LIBRARIES}
${Boost_SYSTEM_LIBRARIES}
