I don't think you can do that.   However, you can make it a little nicer 
with this change:

    MAIN_DEPENDENCY "${CMAKE_CURRENT_SOURCE_DIR}/${filename}"



 From
Note that MAIN_DEPENDENCY is completely optional and is used as a 
suggestion to visual studio about where to hang the custom command.  In 
makefile terms this creates a new target in the following form:

cmake --help-command add_custom_command

          OUTPUT: MAIN_DEPENDENCY DEPENDS
                  COMMAND

However, when you right click on A.lzz and it will run lzz, and not the 
full compiler cycle.  You will have to right click on the generated .cpp 
file to run the actual compiler.  There is no way to collapse that into 
one step.
