[CMake] Qt5Gui can't find glu32 in the system automatically

Qt5GuiConfig.cmake of Qt5Gui of the Desktop OpenGL Qt Version depends on glu32 (and possibly opengl32), but it is not able to find it and exits with
CMake Error at <path>/5.3/msvc2013_64_opengl/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:16 (message):
Failed to find "glu32" in "" with CMAKE_CXX_LIBRARY_ARCHITECTURE "".

I guess Qt5Gui should be able to find its dependencies automatically or at least provide some help for the user on how to fix it.
