title: Unit path compiled in executable
body: <p>I noticed that in compiled exe there are hard-coded paths to 3rd party components units.
  For example, if I use VirtualTrees component, TVirtualStringTree, in compiled executable I can find this path several times:</p>
  
  <pre><code>C:\Program Files\Borland\Delphi7\Source\Virtual Treeview\Source\VirtualTrees.pas
  </code></pre>
  
  <p>This applies to almost all 3rd party components I use, paths to component's units in exe.
  I think this information should not be in executable, but don't know what I have to change in Delphi 7 settings, or in project's settings, to get rid of it.
  Does anyone have a solution please?</p>
