4.windows下使用mingw动态库编译

编译脚本build_debug.bat

@echo off
:: 1. 自动挂载 mingw 环境
call "C:\D\Program\Qt\6.9.0\mingw_64\bin\qtenv2.bat"
:: 2. 运行 CMake Preset
cmake --preset=qt-mingw-dynamic
:: 3. 运行构建
cmake --build --preset=qt-mingw-dynamic -j8
pause

5.windows下使用msvc静态库编译

编译脚本build_realse.bat

@echo off
:: 1. 自动挂载 MSVC 环境
call "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
:: 2. 运行 CMake Preset
cmake --preset=qt-static-release
:: 3. 运行构建
cmake --build --preset=qt-static-release -j8
pause

6.clion中使用

在ToolChain中添加两个脚本与选择编译器

#MSVC
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat
#编译器选择cl.exe

#Qt_Mingw
#只使用gcc/g++编译的不运行的话无需添加
C:\D\Program\Qt\6.9.0\mingw_64\bin\qtenv2.bat

MSVC编译需在CMakePresets.json中启用Qt_MSVC
