I don't know anything about the ExternalData module but assuming this is 
unrelated ...

do you have a target that depends on the new output?
Without one the custom command does not get emitted.

E.g. add_custom_target(foobar ALL DEPENDS 
${CMAKE_BINARY_DIR}/test/data/pacman.e.2.0)
or list it in the sources of an existing add_executable() or 
add_library() target.
