subdirs text file

We have discussed how we want to maintain some of the automake files in the source tree after a package is converted to cmake. Those files provide us an historical record of what was. I notice the subdirs text file no longer is included. That file played a role with using the DO_NOT_COMPILE environment variable, which is helpful with troubleshooting. The DO_NOT_COMPILE options are replaced in cmake with -DWITH options, but the subdirs text file lets us know the cmake conversion is good. Could we get those subdirs files restored to the sources?
