If I start from the template
then I can use it.
its very finicky.
I was unable to put the latest binaries directly in plugins and have it work
if you start from the template project, it has a number of enums and tags in it so gripping works right.

some of the same functionality is in VRMP 2 by inchoate elk, which might work for you
If I use the template I get a decent base that can compile for quest.
