I tried it on both, with cmake2.5 (CVS), but cmake2.4 should be the same
( I was using it before ).

Both rebuild TargetName, as they should.
I did find two bugs that were making the stuff less efficient in the
modified UseSWIG.cmake file I posted.
One due to python files always need regeneration due to their .py files
(I was wrapping stuff for ruby, so it is now more efficient for
languages other than python) and that the swig -MF invocation was also
creating the wrapper needlessly.
There's still one minor gotcha where you can still fool the system not
to detect a dependency change, but it is somewhat obscure so I won't
mention it.

# - SWIG module for CMake
# Defines the following macros:
# SWIG_ADD_MODULE(name language [ files ])
# - Define swig module with given name and specified language
# SWIG_LINK_LIBRARIES(name [ libraries ])
# - Link libraries to swig module
# SWIG_GET_WRAPPER_DEPENDENCIES(swigFile genWrapper language DEST_VARIABLE)
# - Put dependencies of the wrapper genWrapper generated by swig from
# swigFile in DEST_VARIABLE
# All other macros are for internal use only.
# To get the actual name of the swig module,
# use: ${SWIG_MODULE_name_REAL_NAME}.
# Set Source files properties such as CPLUSPLUS and SWIG_FLAGS to specify
# special behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add
# special flags to all swig calls.
# Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify
# where to write all the swig generated module (swig -outdir option)
# The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used
# to specify extra dependencies for the generated modules.
