# General Workflow:
# 1. read all components dirs, a semicolon-separated string (cmake list)
# 2. map the component dir with a unique prefix /COMPONENT_<NAME>_DIR
# 2. write the prefix mapping file to $BUILD_DIR/prefix_map_gdbinit
# 3. print the unique prefix out, a space-separated string, will be used by the build system to add compile options.
