title: z.lib problems while porting qt creator projet to windows
body: <p>I am trying to port a Qt5.9 project from Mac to Windows 10.
  I was able to compile the project easily in a ubuntu installation.
  While trying to build it for windows, i had problems with finding zlib include headers with </p>
  
  <pre><code>#include&lt;zlib.h&gt;
  </code></pre>
  
  <p>That i corrected after following answers here on Stack to</p>
  
  <pre><code>#include&lt;QtZlib/zlib.h&gt; 
  </code></pre>
  
  <p>Now i have problems in LINK phase, it can not open the file z.lib</p>
  
  <p>Problem is i downloaded zlib packages, builds, source code and could not find a z.lib. Only different named libs. Searching in google i could only find people with the same problem, z.lib is not one of the libs included in zlib installation.</p>
  
  <p>This is my project file: </p>
  
  <pre><code>TEMPLATE = app
  
  QT += qml quick widgets websockets
  
  CONFIG += c++11
  
  SOURCES += \
      main.cpp \
      api.cpp \
      app.cpp
  
  HEADERS += \
      api.hpp \
      app.hpp
  
  RESOURCES += qml.qrc
  
  
  LIBS += -lz
  </code></pre>
  
  <p>I tried putting all possible dll and lib files in the project folder. None of them is named z.lib though.</p>
