   9 # This rule build an object (.o) from a source (.cc). It first builds a
  10 # dependency (.d) file which will ensure that the .o is rebuilt whenever the
  11 # header files included by the .cc are updated.
  12 # The options given to GCC for this are as follows:
  13 #  -MM : calculate dependencies, but exclude system headers
  14 #  -MF : output dependencies to the given file
  15 #  -MP : generate "header.h:" rules to avoid errors on deletion of headers
  16 #  -MT : the main rule has the given target (to handle subdirs correctly)
  17 # The .d file is not an explicit target because it will need to be (re-)built
  18 # if and only if the .o needs to be rebuilt.
