Feature/#302 #306 update conan dependencies

Updated the dependencies and now conan 1.0.4 builds builds all of them on my machine. However, we do not have it on the CI runners, so the pipeline does not pass.

As long as we cannot check this with CI, it will break our develop builds. Therefore, it has to remain WIP.

Nevertheless, @ademiralp, @jwendt, @mbellgardt, please check, if everything builds on your local machines with conan >=1.0. Just to make sure it will pass CI once that is updated.

closes #302, #306
