I have one example that does that. It follows annexed.

Here is how to use it:

*# build.jam*
path-constant SOURCE_DIR : externals ;

files = zip unzip ioapi ;

lib minizip : dependencies.svn :
    <include>$(SOURCE_DIR)
    <include>$(SOURCE_DIR)/minizip
    <link>static
    [ conditional <target-os>darwin :
        <define>fopen64=fopen
        <define>fseeko64=fseeko
        <define>ftello64=ftello
        ]
    <svn-output-root>$(SOURCE_DIR)
    <svn-output-header>minizip/$(files).h
    <svn-output-source>minizip/$(files).c
  : # default-build
  : # usage-requirements
    <include>$(SOURCE_DIR)
    <include>$(SOURCE_DIR)/minizip
  ;

*# dependencies.svn*
https://your.svn.server/minizip/v1.1 $(root)/minizip
