twistedcpp is header only so you don't need to build anything. You can either add include/twisted to your compiler include path(e.g.:
-I/path/to/twisted/include or put it to /usr/local/include) or copy the files to your local project. However, twistedcpp depends on boost asio and if the ssl part is used also on openssl. Meaning that you have to link against -lboost_coroutine, -lboost_context, -lboost_system, -lssl and -lcrypto.
More work, help and projects very appreciated.
