ENH: Generate a central list of target directories

This generalizes the previous CMakeFiles/LabelFiles.txt created at the
top of the build tree to a CMakeFiles/TargetDirectories.txt file.  It
lists the target support directories for all targets in the project.
Labels can still be loaded by looking for Labels.txt files in each
target directory.
