I took a quick procrastination-shot at it:
https://github.com/kmatheussen/surge

(first copy various VST directories into the build)
premake5 gmake
make surge-vst2 verbose=1 -j8

ldd -r target/vst2/Debug/Surge-Debug.so

So, a little bit work left, but maybe it's enough to link with a newer
version of
gtkmm than I did.

Don't know how well VSTGUI works on linux though. Using
gtkmm as the underlying GUI to implement VSTGUI on top of
seems worrying.
