# When FIXPATH is set, let it process the file to make sure all paths are usable
# by system native tools. The FIXPATH tool assumes arguments preceeded by an @
# character points to a text file containing further arguments (similar to a
# linker). It replaces any such arguments with a different temporary filename,
# whose contents has been processed to make any paths native. To obtain a
# properly processed compile_commands.json, FIXPATH is then made to invoke an
# AWK script with the unprocessed json file as the only argument, prepended with
# an @ character. The AWK script simply copies the contents of this processed
# file.
#
# The sed command encloses the fragments inside brackets and removes the final
# trailing comma.
