Yes, I did it today for git master branch of wxWidgets under MSys2 UCRT64 MinGW GCC.
I have not yet built Code::Blocks that used it and have no plans to do it in the near future.
Edit: Since someone wanted info I have decided to build wxWidgets today in a MSys2 MinGW package that is easy to build C::B against
I did build Code::Blocks against wx3.3.2 in the past week
