[Cmake] Collecting files from subdirs

[William A. Hoffman]

Each subdir is treated as its own makefile and scope.   Only
cached variables are passed from one sub dir to another.
You have some choices:

1. use the INCLUDE command instead of the SUBDIRS command to include
the lists file in the subdir.
2. List out the sources in the parent directory explicitly
SET(SRCS subdir/file1.cxx subdir/file2.cxx ....)
3. Use AUX_SOURCE_DIRECTORY, but that is really just a variation on 2, its main
use is really having cmake collect all the source names instead of listing 
them one
by one.
