There asre two ways:

You can use the "Case" statement if you use an external/internal 
variable

  type SRC_Type is ( "default", "easy", "advance" ) ;
  --
  SRC : SRC_Type := external ( "SRC", "default" ) ;

  case SRC is
    when "default" =>
        for Source_Files  use ( "libraries_1.adb", 
                                "print_1.adb",
                                "environment_1.ads" ) ;
    when "easy" =>
        for Source_Files  use ( "libraries_2.adb", 
                                "print_1.adb",
                                "environment_2.ads" ) ;
    when "advance" =>
        for Source_Files  use ( "libraries_3.adb", 
                                "print_2.adb",
                                "environment_1.ads" ) ;
  end case;
  --
  -- or you can use the "for Swiches" statement
  --
  package Compiler is
    for Default_Switches ( "Ada" ) use ( "-gnat95" ) ;  -- default 95 specs
    --
    for Switches ( "Program_1.adb" ) use ( "-gnat05" ) ;  -- Ada 2005 specs
    for Switches ( "Program_2.adb" ) use ( "-gnat12" ) ;  -- using Ada 2012
  end Compiler ;
