Or by dragging the vst's dll. from the folder they are stored in, into the Lmms workscreen.
This is a nice list of Vst's, that work well in Lmms.

And, I might have missed them, but I don't seem to see any waves plugins in the list either.
If somehow they do work well in Lmms, and they pass certain standard tests, feel free to post about your findings
so they can be added, to the Lmms Vst wiki list.
And also, welcome to Lmms Forums Main.
