快速编译安卓cpp代码

编译脚本的方式只需要配置一下环境变量 NDK_HOME 即可（ cmake_build.ps1 可以直接放进NDK_build的同级文件，方便我们直接命令行调用）


# Path to ndk
$NDK = $env:NDK_HOME

# Path to cmake
$CMAKE = "cmake"

$BUILD_PATH = "cmake_builds"

# Targets
$ABIs = "arm64-v8a", "armeabi-v7a", "x86", "x86_64"

foreach ($abi in $ABIs) {
    Write-Host "=========================="
    Write-Host "= Building $abi"
    Write-Host "=========================="

    & $CMAKE -S . -B "$BUILD_PATH/$abi" -G "Ninja" `
        -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE `
        -DCMAKE_BUILD_TYPE=Release `
        -DCMAKE_TOOLCHAIN_FILE="$NDK/build/cmake/android.toolchain.cmake" `
        -DANDROID_NDK="$NDK" `
        -DANDROID_ABI="$abi" `
        -DANDROID_NATIVE_API_LEVEL=21

    & $CMAKE --build "$BUILD_PATH/$abi"
}

使用vscode帮我们预处理cmake工程 ( 放在和cmake同级目录即可 )

总的来说还是推荐第二种方式，有个好处就是vscode在安装了cmake插件会帮我识别头文件，打开工程不会出现头文件引入爆红之类的问题，也可以进行快速引用（vscode的引用当然比不上专业的vsstudio，但是一般也算是够用的）
