Building CSoundVST?

How would I go about building CSoundVST on linux using the 5.10 sources? Should I be using my copy of the Steinberg VST SDK 2.4, or is there somewhere else I need to go to get the csound specific sources. As it stands now the sources reference headers in the "frontends/CSoundVST/vst2.4sdk/..." directory tree, which doesn't exist in the CSound sources. Shall I just unpack the Steinberg sources into this directory to get it to work?

Thanks to anyone who can help!
