@neillm @evoskuil I found out where the problem is coming from. The VS-Command Line shows me mysources\libbitcoinmyroot\builds\msvc\vs2017\libbitcoin-system-examples\..\..\..\..\..\libbitcoin-system\include. the example project looks inside libbitcoin-system for include, but my folder is libbitcoinmyroot. renaming the root to libbitcoin-system solves the problem :).
