  4. # Rules for recursively invoking make to build a target in a subproject.
  5. # The format for a recursive target is target@subproject, where "target" is
  6. # one of the standard targets and "subproject" is a subproject directory of the
  7. # current project.  If you want to specify subrojects of subprojects, you
  8. # must reverse-stack them.  For example, the command-line invocation "make 
  9. # prebuild@Grandchild@Child.bproj" will run the prebuild target in the 
  10. # Grandchild subproject of the Child bundle project of the current project.
  11. #
  12. # STANDARD TARGETS
  13. #    clean, mostlyclean, all: see common.make
  14. #    prebuild: see prebuild.make
  15. #    build: see build.make
  16. #    install: see install.make
  17. #    installhdrs: see installhdrs.make
  18. #
  19. # IMPORTED VARIABLES
  20. #    OTHER_RECURSIVE_VARIABLES: The names of variables which you want to be
  21. #      passed on the command line to recursive invocations of make.  Note that
  22. #    the values in OTHER_*FLAGS are inherited by subprojects automatically --
  23. #    you do not have to (and shouldn't) add OTHER_*FLAGS to 
  24. #    OTHER_RECURSIVE_VARIABLES. 
  25. #    T: a non-standard target that you wish to apply recursively.  For example,
  26. #    to build bar.o in the bar subproject, you would execute the command "make
  27. #    foo.o@bar T=foo.o"
