# 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}
|
|
#
|
|
# Example:
|
|
# ANTLR(INPUT MyLexer.g4)
|
|
# ANTLR(INPUT MyParser.g4 DEPENDENCIES MyLexer.cpp)
