may be you could do:

ADD_CUSTOM_COMMAND(TARGET TARGET1
                   COMMAND SAMPLE_COMMAND ARGS ARGUMENTS
                   COMMAND ${CMAKE_COMMAND} -DOutFile=fl.cmake -P
collectFiles.cmake
                   COMMAND ${CMAKE_COMMAND} -DInFile=fl.cmake -P
doPostProcessing.cmake
                   WORKING_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}
                   COMMENT "Doing some stuff"
                   VERBATIM)

the "collectFiles" step will do whatever you want and create the fl.cmake
file
which will be loaded by the second "doPostProcessing" in order to get
access to list of file in a pre-defined CMake var.

You can split this in separate add_custom_command but I don't see the need
in your example.
