title: zlib header not found when cross compiling with mingw?
body: <p>I'm running <code>./configure --host=x86_64-w64-mingw32</code> but for some reason it tells me <code>"zlib header not found."</code>. I have the packages installed(<code>apt-get install zlib1g-gev</code>) but it still tells me this.</p>
  
  <p>When I just run <code>./configure</code> it compiles fine.</p>
  
  <p>I'm trying to cross-compile a 64 bit executable for Windows on Debian 7 with MinGW-64</p>
  
  <p>What must I do to fix this problem or avoid any thing like this?</p>
