CGAL 示例的编译错误

Question

我正在尝试按照官方指南在我的计算机上安装 CGAL：

在使用 vcpkg 安装了 CGAL 和 Qt5 之后，我已经按照描述通过 CMake 生成了 VS 解决方案。 但是现在我在尝试在 VS 中构建解决方案时面临以下错误：

我注意到 vcpkg 安装了 CGAL 4.14，但我尝试编译的示例已经是 5.0。 我检查了 4.14手册，说明 4.14 应该附带示例。 遗憾的是，vcpkg 版本不包含任何示例，我在网上也找不到任何示例。

我的问题是：使用 vcpkg 安装 CGAL 时我是否遗漏了什么？ 我在 Visual Studio 的编译过程中做错了什么吗？ 或者我从哪里得到 4.14 的例子来编译和测试？ 或者他们什么时候将 CGAL 的 vcpkg 版本更新到 5.0？

Answer 1

您有两种解决方案：

• 要么从 github下载完整的 CGAL 4.14 源代码，示例都在其中
• 或者你可以升级你的 vcpkg 以便它下载 CGAL 5.0，通过 git 拉主。
