.SYNOPSIS
|
||
LVGL PC 模拟器一键构建（Visual Studio 版本自适应，x64）。
|
||
|
||
.DESCRIPTION
|
||
不同开发机安装的 VS 版本不同，CMake 生成器必须与本机 VS 大版本一致，
|
||
因此构建入口不写死生成器：本脚本用 vswhere 自动探测本机 Visual Studio
|
||
（VS / BuildTools 均可），按大版本映射 CMake 生成器，取已安装的最高版本：
|
||
16 = "Visual Studio 16 2019"
|
||
17 = "Visual Studio 17 2022"
|
||
18 = "Visual Studio 18 2026"
|
||
若 build/ 目录缓存的生成器与探测结果不一致（换机/升级 VS 后），
|
||
自动删除 build/ 重新配置，避免 MSBuild 报生成器不匹配。
|
||
|
||
退出码：0=成功；1=构建失败；3=环境预检失败（无 cmake / 无 VS / VS 版本过新）。
|
||
|
||
.PARAMETER Config
|
||
构建配置，默认 Debug（可选 Release）。
|
||
|
||
.PARAMETER Clean
|
||
强制删除 build/ 后全量重建。
|
||
|
||
.EXAMPLE
|
||
& 'simulator\build_sim.ps1' # 仓库根目录执行，日常增量构建
|
||
& 'simulator\build_sim.ps1' -Clean # 全量重建
|
||
& 'simulator\build_sim.ps1' -Config Release # Release 构建
