Yeah, it doesn't really look at wxpython at runtime, it's (GRASS_WX64BIT) hardwired from compilation.
GRASS_WXBUNDLED is (was? maybe it's been stripped out?) meant to tell the GUI code somewhere that wxpython is bundled, there was a problem where wxpython wouldn't work, maybe it's fixed now. GRASS_WXBUNDLED is set in custom bundling scripts (not in source).

It says it is trying to find the Python needed by wxPython, but I can see no code that actually checks wxPython. It simply sets GRASS_PYTHONWX to whatever Python it has found, with "pythonw" as a default.

And I can't yet find anything that seems to serve the same function. I can put in a path to the folder/directory where the wxPython 4 files live. While this compiles without error, I don't think it is using wxPython 4.
