解决方法 #

安装extra-cmake-modules包，不同发行版对应命令：

• Debian/Ubuntu系：sudo apt install extra-cmake-modules
• Fedora/RHEL系：sudo dnf install extra-cmake-modules
• Arch系：sudo pacman -S extra-cmake-modules

后续错误：Qt6 qtpaths权限被拒绝 #

解决方法 #

1. 避免用sudo运行cmake：你的Qt安装在用户目录/home/amiroof/Qt/下，root用户无权限访问该目录，直接以普通用户身份重新执行命令：

   cmake -Bbuild -DCMAKE_INSTALL_PREFIX=install -DENABLE_LTO=ON -DLauncher_QT_VERSION_MAJOR=6 -DCMAKE_PREFIX_PATH=/home/amiroof/Qt/6.4.0/msvc2019_64/lib/cmake
   

2. 修复Qt目录权限：确保普通用户对Qt安装目录有读写权限，执行：

   chmod -R u+rwx /home/amiroof/Qt/6.4.0/msvc2019_64/
   

3. 纠正Qt版本选择：你当前指定的是MSVC版本的Qt，这是Windows平台的编译器版本，在Linux上交叉编译Windows程序需要使用MinGW版本的Qt。需下载对应架构的MinGW Qt包，再修改CMAKE_PREFIX_PATH指向正确的MinGW Qt的cmake目录。
