3194 dnl CF_LIB_RULES version: 77 updated: 2015/01/03 11:49:39
3195 dnl ------------
3196 dnl Append definitions and rules for the given models to the subdirectory
3197 dnl Makefiles, and the recursion rule for the top-level Makefile.  If the
3198 dnl subdirectory is a library-source directory, modify the Libs_To_Make list in
3199 dnl the corresponding makefile to list the models that we'll generate.
3200 dnl
3201 dnl For shared libraries, make a list of symbolic links to construct when
3202 dnl generating each library.  The convention used for Linux is the simplest
3203 dnl one:
3204 dnl     lib<name>.so    ->
3205 dnl     lib<name>.so.<major>    ->
3206 dnl     lib<name>.so.<maj>.<minor>
3207 dnl
3208 dnl Note: Libs_To_Make is mixed case, since it is not a pure autoconf variable.
