Build fails on Ubuntu

Issue

I'm running up-to-date Ubuntu 24.04.3 and want to compile osrm-backend to run some travel time calculations. I checked out the osrm-backend repository v6.0.0 and started the build. However, it errored out with the following message:

[ 83%] Linking CXX executable osrm-routed

    inlined from ‘move_assign’ at /usr/include/boost/function/function_template.hpp:1024:24,

make: *** [Makefile:136: all] Error 2

I was able to get the build to finish by going into cmake/warnings.cmake and commenting out add_warning(error), but this doesn't seem ideal.

Steps to reproduce

I think this sequence of commands will do it:

git clone https://github.com/Project-OSRM/osrm-backend.git
cd osrm-backend
git checkout v6.0.0
mkdir build
cd build
cmake ..
make
