This means that your Delphi library path is not properly setup. Please make sure that the folder is included in your library path where vcl.dcp is located, this normally is $(BDS)\lib 
For multi-platform supported Delphi versions, please have a look at

Alternatively you can try to install the packages from the Delphi IDE instead of using msbuild.
