[Lazarus] Lazarus 2.0.12 on Windows x64 cannot build command line program, complains about missing GUI symbols

[Bo Berglund]

I have created a very simple program which is supposed to send a backup zipfile
to a webserver by FTP. I am used to Indy so I use TIdFTP as the object for this
transfer.
I started in lazarus by creating a new program which gave me a very sparse
skeleton only adding Classes as used unit.
I added indylaz to the project dependencies and the uses clause as shown below.

So now I wrote my code and checked it using Run/QuickCompile and it succeeds.
So I tried Run/Compile and get 50 errors, same with Run/Build...

And the error messages are completely wild, here are a few of them:

Compile Project, Target: FtpXferDb.exe: Exit code 1, Errors: 50
Error: Undefined symbol: WSRegisterCustomPage
Error: Undefined symbol: WSRegisterCustomNotebook
Error: Undefined symbol: WSRegisterCustomImageListResolution
Error: Undefined symbol: WSRegisterMenuItem
Error: Undefined symbol: WSRegisterMenu
Error: Undefined symbol: WSRegisterMainMenu
Error: Undefined symbol: WSRegisterPopupMenu
Error: Undefined symbol: WSRegisterDragImageListResolution
Error: Undefined symbol: WSRegisterLazAccessibleObject
Error: Undefined symbol: WSRegisterControl
Error: Undefined symbol: WSRegisterWinControl
....
Error: Undefined symbol: WSRegisterStatusBar
Error: Undefined symbol: WSRegisterTabSheet
Error: Undefined symbol: WSRegisterPageControl
Error: Undefined symbol: WSRegisterCustomListView
Error: Undefined symbol: WSRegisterCustomProgressBar
Error: Undefined symbol: WSRegisterCustomUpDown
Error: Undefined symbol: WSRegisterCustomToolButton

Everything seems to be about GUI stuff which I do not use at all!
This is a command line program....

What can I do to remedy this?

This is my uses clause:

uses
  {$IFDEF UNIX}{$IFDEF UseCThreads}
  cthreads,
  {$ENDIF}{$ENDIF}
  Classes,
  indylaz,
  { you can add units after this }
  SysUtils,
  IniFiles,
  IdFTP,
  IdFTPCommon;
