Try using FOREACH:
FOREACH(root batch-driver ...)

OUTPUT ${Chicken_BINARY_DIR}/${root}.c
MAIN_DEPENDENCY ${root}.scm

COMMAND ${VALID_CHICKEN} ${Chicken_SOURCE_DIR}/${root}.scm
-output-file ${Chicken_BINARY_DIR}/${root}.c ${CHICKEN_FLAGS}
)
ENDFOREACH(root)
That would make all files in FOREACH depend on parameters.scm. Not what
I needed. Previously I was listing out each ADD_CUSTOM_COMMAND
separately because I had different DEPENDS and numbers of DEPENDS for
each of them, and I wanted to get some abstraction in the COMMAND part
only. But I found a better solution per my other post. Best trick is
to create a global variable using file's rootname and a suffix like
'_deplist', then use it to communicate additional data about the file.
This kind of pseudo-OO persistent state technique can be applied to
anything.

The ADD_FILE_DEPENDENCIES macro has a horrible name and was not well
documented or intentionally added to the release. It is meant only
for the deprecated OBJECT_DEPENDS target property. Please ignore its
existence. I'm going to try to get it removed completely in 2.4.3
since it was not in the 2.2 release.
I've hurled and purged. :-)
