C++ qt creator opencv windows cmake错误

我想配置并生成opencv库，以便qt creator链接它们。 我打开了cmake 3.1.0并输入了源代码和构建路径

资料来源：

C:/Users/Philipp_Laptop/Downloads/opencv/sources
build: C:/opencv-mingw

---

然后，我使用以下路径配置了mingw编译器：

C:/Qt/Tools/mingw482_32/bin/gcc.exe
C:/Qt/Tools/mingw482_32/bin/g++.exe

---

成功配置后，我设置了with_Qt选项。 我配置了两次，它显示了以下错误：

为此，我在Windows下使用了CMake GUI，因此我将参考这种方法。 让我们从与

CMAKE\u PREFIX\u路径未定义相关的问题开始。
要解决此问题，只需在CMAKE GUI上按ADD，然后添加名为
CMAKE_PREFIX_PATH
的PATH类型变量，其值
C:/Bin/Qt/5.3/mingw482_32/lib/CMAKE/
，但使用您自己安装的Qt5。您指向的目录现在包含您需要的所有模块：Qt5目录、Qt5AxBase

此时，您按configure，您应该有
QT\u QMAKE\u可执行文件
无效。在我的例子中，您需要正确设置它：
C:/Bin/Qt/5.3/mingw482_32/Bin/qmake.exe

然后再次按配置，查看是否仍存在某些错误（您有其他我从未见过的错误，但可能是前一个错误的结果），在我的情况下，这解决了所有问题，构建继续进行

MINGW配置似乎很好：我只是将bin MINGW路径作为PAT变量的第一个条目，并使用CMAKE的默认编译器（但您的解决方案和我的一样有效）。
Ubuntu是如何找到这些模块的？我从来没有在Ubuntu上指定过
CMAKE\u PREFIX\u路径。

  Policy CMP0054 is not set: Only interpret if() arguments as variables or
