Yes you do:

add_custom_target(save
                             COMMAND ${CMAKE_MAKE_PROGRAM} save
                             WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}
                             COMMENT "Home brewed make save target")


but I wouldn't do that.

I agree that it would be a good feature to be able to change the name
of generated
makefiles, but if you dig the ML you'll see that **after discussion**
there is not
so many **useful** cases to do that.

But you home-brewed Makefile is not cross-platform which is one of the
primary target for using CMake :-]

Moreover you have to described you lib and executable target names
in two places (CMakeLists.txt and home made Makefile) which
opens a window for inconsistency.

You can use add_custom_target and basic CMake scripting for doing just the same.
Look at

file(xxxx ...) commands
