windows - 柯南在生成 CMake 文件时的奇怪行为
问题描述
我目前正在编写一个conanfile.py构建 OpenCV，这是我公司内部使用的自定义构建。我们正在尝试使用 CMake 进行构建，但我们遇到了 OpenCV 的意外行为：在生成 Release 构建而不在设置中指定 build_type 时，OpenCV 会生成发布和调试构建。
这是我们的 conanfile.py：
#!/usr/bin/env python
# -*- coding: utf-8 -*-

请注意它是如何生成 Release 和 Debug 构建的，然后它同时构建了两者。
我们还有一个批处理文件，它使用 CMake 为 OpenCV 生成 Visual Studio 解决方案，然后使用 MSBuild 构建它并且完全按照我们想要的方式工作，所以我怀疑问题出在柯南身上。我们还尝试使用 CMake 助手构建 OpenCV self.run()，结果似乎是一样的。
解决方案
运行安装目标将触发第二次构建，因为它的构建类型与构建命令不同。解决方案是，如果使用 CMake 帮助器，则传递 build_type="Release" 作为构造函数的参数，或者，如果从命令行帮助器运行 CMake，则传递“--config Release”。
