Can't create a package

[PoloNX]

Hello, I want to create a package for borealis. There's already one xmake.lua in it but only support desktop. I want to create one package which support the switch platform. I wanted to use the cmake project
add_deps("cmake") but the CMakeLists.txt at the root of the project is the demo of the lib, not the lib which is located in library/. How can I do to use the other cmake file ?

package("borealis")
    set_homepage("https://github.com/xfangfang/borealis")
    set_description("Hardware accelerated, Nintendo Switch inspired UI library for PC, Android, iOS, PSV, PS4 and Nintendo Switch")
    set_license("Apache-2.0")

    add_urls("https://github.com/xfangfang/borealis.git")
    add_versions("2024.04.18", "03e5fbc79abc65427a7ada91cba5a4ca46d3240b")

    add_deps("cmake")

    on_install(function (package)
        local configs = {}
        table.insert(configs, "-DPLATFORM_SWITCH=ON")
        import("package.tools.cmake").install(package, configs)
    end)

    on_test(function (package)
        assert(package:has_cfuncs("brls::Application::init", {includes = "borealis.hpp"}))
    end)

I just made this but it uses the wrong CMakeLists.txt
