wxLua 3.1.0.0 released
wxLua 3.1.0.0 released
wxLua apps issue against wxw
The current version (https://github.com/pkulchenko/wxlua/) builds with wxwidgets 3.0, 3.1, and the latest 3.1.5. Also, I don't see any issue with wxSTC_LEX_CPP. I don't plan to provide binary releases (given the large number of wxwidgets and Lua versions, compilers and platforms), but you should be able to compile your own binaries using the provided cmake scripts (as you seemed to have done already).
