@XzzX we should add a build with HPX to CI, I guess.

@XzzX without HPX is builds fine, but with HPX is triggers some errors.

HPX error: ``` /usr/include/hpx/type_support/pack.hpp:49:20: error: use of undeclared identifier '__integer_pack' 49 | : index_pack | ^ /usr/include/hpx/type_support/pack.hpp:49:37: error: pack expansion does not contain any unexpanded parameter packs 49 | :...

Is this from mixing gcc-hpx with clang?

Ok, I chatted with @opensdh and @diehlpk, the above issue should be fixed in hpx-1.10.0, but due to a bug in the Fedora spec the openmpi subpackage didn't get deployed...

hpx-1.10 has arrived in Fedora. Now there is: ``` 2024-09-01T17:26:19.0186884Z /__w/espressopp/espressopp/src/hpx4espp/integrator/LangevinThermostat.cpp:93:39: warning: 'not_implemented' is deprecated: The unscoped hpx::error names are deprecated.

@hkaiser thanks, we will try to update the code to not use depreciated hpx features.

@hkaiser, what should we use instead of ` HPX_THROW_EXCEPTION(hpx::not_implemented, ...)` ?

@hkaiser got it, I think.

@XzzX can you have a quick look at: ``` 2024-09-12T18:54:51.4636924Z [ 5%] Building CXX object src/hpx4espp/CMakeFiles/_hpx4espp_component.dir/storage/DomainDecomposition.cpp.o 2024-09-12T18:54:51.4647616Z cd /__w/espressopp/espressopp/build/src/hpx4espp && /usr/bin/ccache /usr/lib64/ccache/clang++ -DHPX4ESPP_ENABLED=1 -DHPX_LIBRARY_EXPORTS -D_hpx4espp_component_EXPORTS -I/__w/espressopp/espressopp/src -I/__w/espressopp/espressopp/src/include -I/__w/espressopp/espressopp/build/src -isystem /usr/include/openmpi-x86_64...
