  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.

  The imported target "Qt5::Gui" references the file

  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

对于配置生成器，由于我将其用于IDE，因此我使用了Visual Studio 15 2017.无论如何，这可以解决吗?

For the configuration generator I used Visual Studio 15 2017 since I'm using that for my IDE. Is there anyway that this can be solved?

推荐答案

请尝试使用最新版本的assimp(4.1.0).cygwin-cmake文件已损坏.这将与最新版本一起使用.

Please try the latest version of assimp ( 4.1.0 ). The cygwin-cmake file was broken. This shall work with the latest version.

作为一种解决方法，可以使用assimp的工具支持(将构建库，但不构建基于qt5的查看器):

As a workaround diable the tools-support for assimp ( the library will be build, but the qt5-based viewer not ):

cmake CMakelists.txt -DASSIMP_BUILD_ASSIMP_TOOLS=OFF

这将解决您的cmake错误，因为这些工具不会受到cmake的影响.

This will fix your cmake-error, because the tools will not be affected by cmake.
