The configure command will only copy files when cmake is run. Another option is to create a new target, and use the custom_command option. Here's one that I use (if you run it more than once, you'll have to modify the add_custom_target line to make it unique for each call).

macro(copy_files GLOBPAT DESTINATION)
  file(GLOB COPY_FILES
    RELATIVE ${CMAKE_CURRENT_SOURCE_DIR}
    ${GLOBPAT})
  add_custom_target(copy ALL
    COMMENT "Copying files: ${GLOBPAT}")

  foreach(FILENAME ${COPY_FILES})
    set(SRC "${CMAKE_CURRENT_SOURCE_DIR}/${FILENAME}")
    set(DST "${DESTINATION}/${FILENAME}")

    add_custom_command(
      TARGET copy
      COMMAND ${CMAKE_COMMAND} -E copy ${SRC} ${DST}
      )
  endforeach(FILENAME)
endmacro(copy_files)
