If there's no way to perform a simple text substitution on a custom
build rule's COMMAND line, then that's really really irritating. I
already had to expand out all my build rules into explicit
ADD_CUSTOM_COMMAND statements, because only DEPENDS works on
source-file-to-source-file dependencies.
Try using FOREACH:
FOREACH(root batch-driver ...)
ADD_CUSTOM_COMMAND(
OUTPUT ${Chicken_BINARY_DIR}/${root}.c
MAIN_DEPENDENCY ${root}.scm
DEPENDS parameters.scm
COMMAND ${VALID_CHICKEN} ${Chicken_SOURCE_DIR}/${root}.scm
-output-file ${Chicken_BINARY_DIR}/${root}.c ${CHICKEN_FLAGS}
)
ENDFOREACH(root)

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.
