qt - cmake 上的 Windows 错误将 Opencv 与 Qt 链接

问题描述

我正在尝试通过使用 cmake 添加我的 opencv 并为 Qt 贡献模块，例如此视频https://www.youtube.com/watch?v=NwLkwfCt9mM&t=191s

但是我安装了Qt并像这样添加了系统变量的路径： C:/Users/Gökhan/Desktop/cmake-3.19.8-win64-x64/bin C:/Qt/Qt5.12.11/Tools/mingw730_64/bin C:/ Qt/Qt5.12.11/5.12.11/mingw73_64/bin

当我试图将 opencv 添加到 qt cmake 时说：

Error in configuration process, project files may be invaild.

这是写在下划线中的错误：

CMake Error at C:/Users/Gökhan/Desktop/cmake-3.19.8-win64-x64/share/cmake-3.19/Modules/CMakeTestCXXCompiler.cmake:59 (message):
  The C++ compiler

    "C:/Qt/Qt5.12.11/Tools/mingw730_64/bin/g++.exe"

无法编译简单的测试程序。

它失败并显示以下输出：

我已经检查了解决方案，但我使用 Windows 8 的方式无法实现任何目标
