CMake Qt5Gui build error

I am following this quick start guide on the opentrack project and I get an error when I try to build it:

CMake Error at cmake/opentrack-qt.cmake:3 (find_package):
  By not providing "FindQt5Gui.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5Gui", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Gui" with any
  of the following names:

    Qt5GuiConfig.cmake
    qt5gui-config.cmake

  Add the installation prefix of "Qt5Gui" to CMAKE_PREFIX_PATH or set
  "Qt5Gui_DIR" to a directory containing one of the above files.  If "Qt5Gui"
  provides a separate development package or SDK, be sure it has been
  installed.

I recorded a video for clarity to show that I have everything installed and set properly:

I have Qt installed in G:\Programs\Qt and CMake installed in G:\Programs\CMake.

What to do to fix it? I tried googling it but with no success: there are no solutions for it and even no issues containing word Qt5Gui on this repository.
