As stated above, all the documentation has moved. Please refer to the version of this tutorial that is kept up to date. It is linked from this page:
CommonAPI C++ and bindings have been moved to github, see overview at https://github.com/orgs/GENIVI/teams/someip/repositories and see also the CommonAPI C++ homepage at http://genivi.github.io/capicxx-core-tools/. Please make sure that you use code generators and runtime libraries with the same version by getting the code generator binaries from capicxx-core-tools/releases repository, capicxx-dbus-tools/releases repository and capicxx-someip-tools/releases repository. Otherwise you could get same strange compilation errors. Please note that a newer version of this wiki page can be accessed via capicxx-core-tools/wiki repository.
