在 Cmake 中构建 Assimp 时出错

Question

您好，我正在尝试使用 Cmake 构建 Assimp，但每次我尝试配置 Assimp 时都会出现以下错误消息。 Cmake的版本是3.11.0，assimp是4.0.0.

  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 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，我使用了 Visual Studio 15 2017，因为我将它用于我的 IDE。无论如何，这可以解决吗？

Answer 1

请尝试最新版本的assimp ( 4.1.0 )。 cygwin-cmake 文件已损坏。这将适用于最新版本。

作为解决方法，禁用对 assimp 的工具支持（将构建库，但不会构建基于 qt5 的查看器）：

cmake CMakelists.txt -DASSIMP_BUILD_ASSIMP_TOOLS=OFF

这将修复您的 cmake 错误，因为这些工具不会受到 cmake 的影响。
