Not like this. 

You'll have to do this with the unit path:

  Case OS of
    Windows : begin
              T.UnitPath:='corelib/gdi';
              T.AddDependency('gfx_gdi');
              end;
    linux   : begin
              T.UnitPath:='corelib/x11';
              T.AddDependency('gfx_x11');
              end;
    // etc.
  end;

Obviously, the fpmake program is a normal pascal program, so you can do
complicated stuff like this:

-----------------------------------------------------------------------

program fpmake;

Type 
  TWidgetSet = (wsGDI,wsX,wCarbon);

Var
  WidgetSet : TWidgetSet;

procedure DetermineWidgetSet;

Var
  I : Integer;

begin
  Case Installer.OS of
    Windows : WidgetSet:=wsGDI;
    Linux : Widgetset:=wsX;
    macos : WidgetSet:=wsCarbon
  end;
  // Check paramstr() to see if the widgetset was overridedn on the commandline;
  For I:=1 to ParamCount do
    If ParamStr(i)='--widgetset=X' then
      WidgetSet:=wsX;
end; 

begin
  DetermineWidgetSet;
  With Installer do
   /// .... 
   Case WidgetSet of
    wsGDI : T.UnitPath:='corelib/gdi';
    wsX   : T.UnitPath:='corelib/x11';
    // etc.
   end;
  ...
  Run;
  end;

Default for the FPC installation, or to installdir
You can do a 

  fpmake --baseinstalldir='c:\program files\my package';

or set the default directory in the fpmake source code.

It's super configurable. 

A 

./fpmake --help 

will give you all options, in good unix tradition :-)

Michael.
