CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfig.cmake:27 (message):
  The imported target "Qt5::Gui" references the file

     "/usr/lib/x86_64-linux-gnu/libEGL.so"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake"

  but not all the files it references.
