# SOURCE_FILE and INCLUDE_DIRS are variables that are either absolute
# paths to the .C file being compiled and the include directories if
# we're building with gcov, or else they are relative paths
# otherwise. The key thing to remember is that they are lazily
# expanded, so they're relevant to whatever rule they're used in. We
# don't want to always have absolute paths because of build
# performance and because it causes the build output with
# BUILD_VERBOSE to be larger and less readable.
