  98 #--------------------------------------------------------------------
  99 #       The statements below define a collection of symbols related to
 100 #       dynamic loading and shared libraries:
 101 #
 102 #       CMAKE_SHLIB_CFLAGS -    Flags to pass to cc when compiling the components
 103 #                       of a shared library (may request position-independent
 104 #                       code, among other things).
 105 #       CMAKE_SHLIB_LD_LIBS -   Dependent libraries for the linker to scan when
 106 #                       creating shared libraries.  This symbol typically
 107 #                       goes at the end of the "ld" commands that build
 108 #                       shared libraries. The value of the symbol if
 109 #                       "${LIBS}" if all of the dependent libraries should
 110 #                       be specified when creating a shared library.  If
 111 #                       dependent libraries should not be specified (as on
 112 #                       SunOS 4.x, where they cause the link to fail, or in
 113 #                       general if Tcl and Tk aren't themselves shared
 114 #                       libraries), then this symbol has an empty string
 115 #                       as its value.
 116 #       CMAKE_SHLIB_SUFFIX -    Suffix to use for the name of the shared library.  An
 117 #                       empty string means we don't know how to use shared
 118 #                       libraries on this platform.
 119 #       CMAKE_SHLIB_BUILD_FLAGS -
 120 #                       Flags to use when building a shared library.
 121 #       CMAKE_SHLIB_LINK_FLAGS -
 122 #                       Flags to pass to the compiler when linking object
 123 #                       files into an executable application binary such
 124 #                       as tclsh.
 125 #       CMAKE_SHLIB_RUNTIME_FLAG -
 126 #                       Flag used to specify the runtime directories (e.g. "-R" or
 127 #                       "-Wl,-rpath,"). If null, no attempt is make to specify the
 128 #                       runtime paths.
 129 #       CMAKE_SHLIB_RUNTIME_SEP -
 130 #                       If null, then each path is a separate argument. If not null,
 131 #                       then all the directories are joined together, separated by
 132 #                       $(CMAKE_SHLIB_RUNTIME_SEP) and appended to
 133 #                       $(CMAKE_SHLIB_RUNTIME_FLAG). When not null, this is
