如何知道使用VCPKG安装的库的名称？

Question

在我使用 cmake 构建的简单应用程序中，我使用 opencv，它是随 vcpkg 安装的。

在 CMakeLists.txt 上，我必须 find_package(OpenCV REQUIRED)，用 opencv 替换 OpenCV 将使构建失败。

从 vcpkg list 我看到 opencv 已安装。

那么我应该从哪里获得正确的拼写OpenCV？

再次执行安装包的命令对 opencv 没有帮助。

./vcpkg install opencv

它只是每次都提到opencv，而不是OpenCV。

Answer 1

1. CMAKE模块/配置名称不等于VCPKG端口名称
2. 启动。
3. VCPKG可能会打印用法消息（如果您的VCPKG已经足够新并且启发式 文档如何工作方式：

在此模式下，cmake搜索一个称为＆lt; lowerCasepackageName＆gt; -config.cmake或＆lt; packagename＆gt; config.cmake。

- ＆gt;因此，我推断出OPENCV安装一个名为OpenCvConfig.cmake.cmake的配置文件，该文件由VCPKG文件列表备份：

opencv4:x64-windows:/share/opencv/OpenCVConfig-version.cmake
opencv4:x64-windows:/share/opencv/OpenCVConfig.cmake
