title: CMake linking library doesn't show up in VisualStudio generated project
body: <p>I am generating a VisualStudio project for Windows with cmake and the provided linking functions don't appear to work on the generated VisualStudio project.</p>
  
  <p>The generated project is a library and it relies on another library as a dependency.</p>
  
  <p>Generation of the project works fine but nothing appears under "Additional Dependencies" entry whatever i try.</p>
  
  <p>I tried using both "link_libraries" and "target_link_libraries", both before and after stating "add_library( MyLib )"
  I tried this for instance:</p>
  
  <pre><code>project( MyLib )
  ...
  add_library( MyLib ${source_list} )
  ...
  target_link_libraries ( MyLib ${SOME_LIB_PATH} )
  target_link_libraries ( MyLib "${SOME_LIB_PATH}" )
  target_link_libraries ( MyLib W:/work/Project/MyLib/ )
  target_link_libraries ( MyLib "W:/work/Project/MyLib/" )
  target_link_libraries ( MyLib W:/work/Project/MyLib/MyLib.lib )
  target_link_libraries ( MyLib "W:/work/Project/MyLib/MyLib.lib" )
  target_link_libraries ( MyLib banane )
  target_link_libraries ( MyLib whatever )
  target_link_libraries ( MyLib "test" )
  ...
  include_directories(
      "Include/"
      ${SOME_LIB_INCLUDE_PATH}
  )
  </code></pre>
  
  <p>Include directories appear correctly in the project properties though.
  So is that a bug or am i missing something :) ?</p>
