forked from jasder/antlr
Updated CMake for demo to:
- Only require JRE - Support out of tree build from antlr repostitory - Support Superproject build with ExternalAntlr4Cpp cmake module ExternalAntlr4Cpp module has quickstart documentation for people to be able to start working quicly with antlr4cpp from the base demo sources see source file for example.

# create your project source folder somewhere. e.g. ~/srcfolder/

# + make a subfolder cmake
|

# + Copy this file to srcfolder/cmake
|

# + cut below and use it to create srcfolder/CMakeLists.txt,
|

# + from https://github.com/DanMcLaughlin/antlr4/tree/master/runtime/Cpp/demo Copy main.cpp, TLexer.g4 and TParser.g4 to ./srcfolder/
|

# next make a build folder e.g. ~/buildfolder/
