antlr-cmake-starter's Issues

download.sh

Hi,
thank you for your example. I noticed, that the source zip uri changed, so the download.sh script needs to be adapted (incl. version upgrade) to:

cd "$(dirname "$0")"
top=$(pwd)

mkdir -p cpp_runtime

Download ANTLR and the CPP runtime

curl http://www.antlr.org/download/antlr-4.8-complete.jar -o antlr.jar
curl https://codeload.github.com/antlr/antlr4/zip/4.8 -o cpp_runtime/archive.zip

Unzip cpp runtime

cd cpp_runtime
unzip archive.zip

Parser and Lexer in one flle

Is possible add these handling ?
My trial of change original function:

# Function
#   ANTLRone(INPUT <input>)
#
# Description:
#   Take an ANTLR file and produce a CMake rule to generate the corresponding
#   C++ files.
#
# Notes:
#   The ANTLR file path must be relative to ${CMAKE_CURRENT_SOURCE_DIR}
#   Parser and lexer in one file.
#
# Example:
#   ANTLRone(My1.g4)
function(ANTLRone)
  set(source ${ARGN})
