title: QMake: Referencing a library using relative paths
body: <p>I have a Qt project using SQLite, so I have the following directory structure:</p>
  
  <pre><code>C:\Workspace\MyProject\MyProject.pro
  C:\Workspace\MyProject\sqlite3\sqlite3.lib
  </code></pre>
  
  <p>Adding sqlite3.lib with absolute paths works fine:</p>
  
  <pre><code>LIBS += -L"c:/Workspace/MyProject/sqlite3" -lsqlite3
  </code></pre>
  
  <p>But I can't make it work with relative paths. I try with:</p>
  
  <pre><code>LIBS += -L"sqlite3" -lsqlite3
  </code></pre>
  
  <p>But that fails with:</p>
  
  <pre><code>:-1: error: LNK1104: cannot open file 'sqlite3\sqlite3.lib'
  </code></pre>
  
  <p>I tried but <code>LIBS += -L"../sqlite3"</code> or even <code>LIBS += -L"../../sqlite3"</code>, but that didn't work either.</p>
  
  <p>I'm using MSVC 2008 for the compiler toolchain.</p>
