# When absolute paths are not allowed in the output, and the compiler does not
# support any options to avoid it, we need to rewrite compile commands to use
# relative paths. By doing this, the __FILE__ macro will resolve to relative
# paths. The relevant input paths on the command line are the -I flags and the
# path to the source file itself.
#
# The macro MakeCommandRelative is used to rewrite the command line like this:
# 'CD $(WORKSPACE_ROOT) && <cmd>'
# and changes all paths in cmd to be relative to the workspace root. This only
# works properly if the build dir is inside the workspace root. If it's not,
# relative paths are still calculated, but depending on the distance between the
# dirs, paths in the build dir may end up as essentially absolute anyway.
#
# The fix-deps-file macro is used to adjust the contents of the generated make
# dependency files to contain paths compatible with make.
