Can you try building the Qt C++ 'minimal' example from the 
'webenginewidgets' sub-directory of a normal Qt installation? If that 
works then we know the original file is Ok.

Does a code signature depend on a file's location in the filesystem? If 
so that's a problem as that location is obviously not known when the 
wheel is created.
