text: How to build
  =====================
  
  The instructions should help you build the Installer Framework from scratch.
  
  
  Get the sources
  ---------------------
  
  Use Git to check out the Qt Installer Framework sources that are hosted at:
  
  http://code.qt.io/cgit/installer-framework/installer-framework.git/
  
  
  Build a static Qt
  ---------------------
  
  Building the Qt Installer Framework from sources requires at least Qt version 5.12.7.
  Supported compilers are MSVC 2013 or newer, GCC 4.7 or newer,
  and Clang 3.1 or newer. Currently, the tested combination for Windows is Qt 5.12.7 with MSVC 2015.
  
  If you want to ship your installer as a single file you have to build
  Qt and the Qt Installer Framework statically.
  
  See the Qt documentation for the prerequisites and steps to build Qt from sources.
  Please read SSL Import and Export Restrictions from http://doc.qt.io/qt-5/ssl.html if
  you are statically linking against OpenSSL libraries.
  
  ### Windows
  
  Recommended configuration options for Microsoft Windows:
  
  configure -prefix %CD%\qtbase -release -static -static-runtime -accessibility -no-icu -no-sql-sqlite -no-qml-debug -nomake examples -nomake tests
  Build Qt:
  nmake (or 'mingw32-make') module-qtbase module-qtdeclarative module-qttools module-qttranslations module-qtwinextras
  ### Linux
  
  Recommended configuration options for Linux:
  
  configure -prefix $PWD/qtbase -release -static -accessibility -qt-zlib -qt-libpng -qt-libjpeg -qt-xcb -qt-pcre -no-glib -no-cups -no-sql-sqlite -no-qml-debug -no-opengl -no-egl -no-xinput2 -no-sm -no-icu -nomake examples -nomake tests -no-libudev
  Build Qt:
  make module-qtbase module-qtdeclarative module-qttools module-qttranslations
  ### macOS
  
  Recommended configuration options for macOS:
  
  configure -prefix $PWD/qtbase -release -static -no-securetransport -accessibility -qt-zlib -qt-libpng -qt-libjpeg -no-cups -no-sql-sqlite -no-qml-debug -nomake examples -nomake tests -no-freetype
  Build Qt:
  make module-qtbase module-qtdeclarative module-qttools module-qttranslations
  
  
  Build the Framework
  ---------------------
  
  Run 'qmake && make' (or 'mingw32-make', 'nmake' ...) to build the Qt Installer
  Framework. The documentation can be generated by 'make docs'.
