title: Building Qt PostgreSql Driver
body: <p>i have been trying to build the Qt Driver for 2 weeks now , without succeed.
  I even moven on windows xp 32 Bit to avoid compatibility Problem with the 64 bit (which i faced when trying to link Psql libraries to my C Program).
  Using a normal C compiler does function but when i want to have a GUI.
  I tried 
  qmake -o Makefile "INCLUDEPATH+=D:/Programme/PostgresSQL/9.0/include" "LIBS+=D:/Programme/PostgresPlus/9.0/lib(or /lib/libpq.lib)" psql.pro 
  it generates Makefile debug and release
  Now when i try : mingw32-make debug or release or even just mingw32-make</p>
  
  <pre><code>D:\Qt\2010.05\qt\src\plugins\sqldrivers\psql&gt;mingw32-make
  mingw32-make -f Makefile.Debug all

  </code></pre>
  
  <p>I really have no idea what this missing -lpq might be.
  Thanks for Helping.
