  69 #--------------------------------------------------------------------
  70 #       The statements below define a collection of symbols related to
  71 #       dynamic loading and shared libraries:
  72 #
  73 #       CMAKE_SHLIB_CFLAGS -    Flags to pass to cc when compiling the components
  74 #                       of a shared library (may request position-independent
  75 #                       code, among other things).
  76 #       CMAKE_SHLIB_LD_LIBS -   Dependent libraries for the linker to scan when
  77 #                       creating shared libraries.  This symbol typically
  78 #                       goes at the end of the "ld" commands that build
  79 #                       shared libraries. The value of the symbol if
  80 #                       "${LIBS}" if all of the dependent libraries should
  81 #                       be specified when creating a shared library.  If
  82 #                       dependent libraries should not be specified (as on
  83 #                       SunOS 4.x, where they cause the link to fail, or in
  84 #                       general if Tcl and Tk aren't themselves shared
  85 #                       libraries), then this symbol has an empty string
  86 #                       as its value.
  87 #       CMAKE_SHLIB_SUFFIX -    Suffix to use for the name of the shared library.  An
  88 #                       empty string means we don't know how to use shared
  89 #                       libraries on this platform.
  90 #       CMAKE_SHLIB_BUILD_FLAGS -
  91 #                       Flags to use when building a shared library.
  92 #       CMAKE_SHLIB_LINK_FLAGS -
  93 #                       Flags to pass to the compiler when linking object
  94 #                       files into an executable application binary such
  95 #                       as tclsh.
  96 #       CMAKE_SHLIB_RUNTIME_FLAG -
  97 #                       Flag used to specify the runtime directories (e.g. "-R" or
  98 #                       "-Wl,-rpath,"). If null, no attempt is make to specify the
  99 #                       runtime paths.
 100 #       CMAKE_SHLIB_RUNTIME_SEP -
 101 #                       If null, then each path is a separate argument. If not null,
 102 #                       then all the directories are joined together, separated by
 103 #                       $(CMAKE_SHLIB_RUNTIME_SEP) and appended to
 104 #                       $(CMAKE_SHLIB_RUNTIME_FLAG). When not null, this is
 105 #                       typically a colon ":".
