The options are:
* `PACKAGE` - defines a namespace for the generated C++ files
* `OUTPUT_DIRECTORY` - the output directory for the generated files. By default it uses ${CMAKE_CURRENT_BINARY_DIR}
* `OUTPUT_DIRECTORY` - the output directory for the generated files. By default it uses `${CMAKE_CURRENT_BINARY_DIR}`
* `DEPENDS_ANTLR` - the dependent target generated from antlr_target for the current call
* `COMPILE_FLAGS` - additional compile flags for ANTLR tool
* `DEPENDS` - specify the files on which the command depends. It works the same way `DEPENDS` in [add_custom_command()](https://cmake.org/cmake/help/v3.11/command/add_custom_command.html)

`ANTLR4_TAG` is set to master branch by default to keep antlr4 updated. However, it will be required to rebuild after every `clean` is called. Set `ANTLR4_TAG` to a desired commit hash value to avoid rebuilding after every `clean` and keep the build stable, at the cost of not automatically update to latest commit.
