 ####Qt
 In order for CMake to find the Qt5 find modules, you will need to set an ENV variable pointing to your Qt installation.
 
-For example, a Qt5 5.3.2 installation to /usr/local/qt5 would require that QT_CMAKE_PREFIX_PATH be set with the following command. This can either be entered directly into your shell session before you build or in your shell profile (e.g.: ~/.bash_profile, ~/.bashrc, ~/.zshrc - this depends on your shell and environment).
+For example, a Qt5 5.4.0 installation to /usr/local/qt5 would require that QT_CMAKE_PREFIX_PATH be set with the following command. This can either be entered directly into your shell session before you build or in your shell profile (e.g.: ~/.bash_profile, ~/.bashrc, ~/.zshrc - this depends on your shell and environment).
 
 The path it needs to be set to will depend on where and how Qt5 was installed. e.g.
 
-    export QT_CMAKE_PREFIX_PATH=/usr/local/qt/5.3.2/clang_64/lib/cmake/
