[CMake] Passing back list of files from Function

2012-05-11 Thread Michael Jackson 
I have a function where I am generating a number of files and I need to pass 
that list of files back to the original calling cmake command/file/scope. How 
would I go about that?



function(create_files)
  set(options)
  set(multiValueArgs GENERATED_HEADERS)
  cmake_parse_arguments( WIG ${options} ${oneValueArgs} ${multiValueArgs} 
${ARGN} )

  foreach ()
 .. Generate some files

  endforeach()


??

endfunction()


set(headers )
create_files (GENERATED_HEADERS headers)


Could someone help me fill in the blanks? Thanks

Give the name of a variable to create_files() which will be used to return the 
values:

function(create_files)
  set(options)
  set(multiValueArgs GENERATED_HEADERS)
  cmake_parse_arguments( WIG ${options} ${oneValueArgs}
${multiValueArgs} ${ARGN} )
 
  foreach ()
 .. Generate some files

  endforeach()

  # the following line sets generatedFiles to file[123].x
  set(${outVar} file1.x file2.x file3.x PARENT_SCOPE)

endfunction()

 
 
set(headers foo.h bar.h blub.h)
set(generatedFiles )
create_files (GENERATED_HEADERS INFILES ${headers} OUTVAR generatedFiles)
