[CMake] custom command comments not showing up

[Craig Scott]

Unfortunately, COMMENT is unreliable. Some generators will honour it,
others won't. A more robust alternative is to use CMake's command mode to
echo the comment instead. Eg:

add_custom_command( TARGET zApp_zip POST_BUILD
        COMMAND ${CMAKE_COMMAND} -E echo "test2"
        COMMAND ${CMAKE_COMMAND} ARGS ...snip...
    )
