# this script configures the cmake project and generates
# two versions of compile_commands.json
# one is the original version, which has triple escapes by ROS
# the other has triple escaped ROS_PACKAGE_NAME macros replaced
# e.g. -DROS_PACKAGE_NAME=\\\"robot_interface\\\"
# becomes -DROS_PACKAGE_NAME=\"robot_interface\"
