CMake error：找不到Ninja

[beiyuming]

已经按文档命令尝试构建，但是cmake提示找不到Ninja，且CMAKE_MAKE_PROGRAM 没有设置
cmake完整指令及报错：
$ cmake -DCMAKE_PREFIX_PATH="D:\CS\QT\6.8.1\mingw_64" -DCMAKE_BUILD_TYPE=Release -GNinja "D:\CS\QT\projects\FluentUI" CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to sel ect a different build tool. CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage -- Configuring incomplete, errors occurred!

可以手动安装Ninja或者使用Qt Maintenance Tool选择安装Ninja组件

非常感谢，是这个问题没错，我在环境变量Path里加上nanja解决这个报错。
但是还是无法编译，不知道是否是因为默认选择编译器问题？（电脑里有多个mingw，且qt的mingw并没有加到系统变量中，其次gt的g++编译器似乎不在<QT_SDK_DIR_PATH>的mingw而在其QT目录的tool工具下的mingw。原谅我对构建原理不太熟悉，昨晚尝试一晚上都没办法配好这个环境 T T

我系统变量里的g++ 是8.1，而qt安装的g++是13.1（没有加到系统变量中），是否是因为这个原因导致Undefine呢？我想直接将系统变量里的g++路径换成qt的，但是我不清楚这两个mingw是否有什么特殊区别，不知道可不可以这么做。
以下是我运行Camke的命令及其提示信息：

修改gcc路径后似乎还是一样的问题，实在不知道怎么办了T T

尝试执行ninja后，也确实存在问题

可能是因为你使用的QT6.8.1导致的，项目中使用的是QT6.2.4，你可以重新安装QT6.2.4版本试下

没有向前兼容吗o.O,我试试看吧
