Ошибка при сборке Assimp в Cmake

Привет, я пытаюсь собрать Assimp с помощью Cmake, но следующее сообщение об ошибке появляется каждый раз, когда я пытаюсь настроить Assimp. Версия Cmake - 3.11.0, а assimp - 4.0.0.

CMake Deprecation Warning at contrib/zlib/CMakeLists.txt:8 (cmake_policy):
  The OLD behavior for policy CMP0048 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

CMake Error at C:/cygwin/lib/cmake/Qt5Gui/Qt5GuiConfig.cmake:27 (message):
  The imported target "Qt5::Gui" references the file

     "C:/cygwin/include/qt5/"

  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

     "C:/cygwin/lib/cmake/Qt5Gui/Qt5GuiConfig.cmake"

  but not all the files it references.

В качестве генератора конфигурации я использовал Visual Studio 15 2017, так как я использую его для своей IDE. Есть ли способ решить эту проблему?
