find vcpkg directory: $ xmake l detect.sdks.find_vcpkgdir

We can download https://github.com/tboox/xmake/releases/download/v2.2.1/xmake-v2.2.2-dev.exe and try it.

xmake will attempt to detect the vcpkg root directory automatically if we have executed $ vcpkg integrate install.

And we can also set the vcpkg directory manually.

$ xmake f --vcpkg=f:\vcpkg

Find and add package.

target("test")
    on_load(function (target)
        import("lib.detect.find_package")
        target:add(find_package("zlib"))
    end)
