无法构建简单的QT5项目

问题描述 投票：0回答：1

我使用本教程为Windows设置了QT-https://wiki.qt.io/MinGW-64-bit

我需要使用CMAKE

[我在qtcreator中创建了一个空项目，但是当我尝试将其弄乱时，出现此错误：

Starting to parse CMake project, using: "-DCMAKE_BUILD_TYPE:STRING=Debug", "-DCMAKE_CXX_COMPILER:STRING=C:/msys64/mingw64/bin/g++.exe", "-DCMAKE_CXX_COMPILER_TARGET :STRING=x86_64-pc-msys", "-DCMAKE_C_COMPILER:STRING=C:/msys64/mingw64/bin/gcc.exe", "-DCMAKE_C_COMPILER_TARGET:STRING=x86_64-pc-msys", "-DCMAKE_PREFIX_PATH:STRING=C:/msys64/mingw64", "-DCMAKE_SYSROOT:STRING=C:/msys64", "-DQT_QMAKE_EXECUTABLE:STRING=C:/msys64/mingw64/bin/qmake.exe".

    "C:/msys64/mingw64/bin/g++.exe"

  is not able to compile a simple test program.

  It fails with the following output:

CMake Project parsing failed.

此字符串似乎有错误：

 C:msys64mingw64bing++.exe

因为斜杠处理不正确。

那么我该如何解决？设置存储在哪里？

UPDATE 1

这是我的CMakeLists.txt

好吧，我修复了它，看来忍者工具会导致Windows下的所有问题！
