makes the libantlr4-runtime.dll. Working on issues after that with building :Utf8Test.cpp

I also met a similar error when compiling antlr4-runtime. But the difference is that I compiled it into DLL on linux using x86_64-w64-mingw32-g++-posix, and the whole error msg is like:

error: definition of static data member ‘antlr4::CommonToken::EMPTY_SOURCE’ of dllimport’d class
   23 | const std::pair<TokenSource*, CharStream*> CommonToken::EMPTY_SOURCE;
      |                                            ^~~~~~~~~~~
make[2]: *** [CMakeFiles/antlr4_static.dir/build.make:167：CMakeFiles/antlr4_static.dir/src/CommonToken.cpp.o]

Thank you for any suggestions!

I fixed this error by adding the code #define ANTLR4CPP_STATIC at the top of antlr4-common.h. As mentioned here in the docs, you need to define ANTLR4CPP_STATIC if you are compiling the runtime to make a static lib in order for certain classes to not be defined multiple times, hence the error messages.
