Returning values from a cmake macro

Question

I would like to create a cmake macro which fills in a given variable with some values, for example:

macro ( fillList list )    
    set( list a b c )
endmacro()

fillList( list )

This doesn't seem to be possible with cmake. Any suggestions for achieving this in cmake?

Answer 1

Pass the name of the variable and use that:

macro(fillList list)
  set(${list} a b c)
endmacro()
