使用 xmake package 的疑问？

[KaivnD]

我有一个xmake项目大概是这样

liba 的 xmake.lua 有两个target，一个是静态库，另一个是单元测试

-- https://github.com/myrepo/liba.git
add_rules("mode.debug", "mode.release")

add_requires("gtest")
add_requires("pybind11")

target "liba"
    set_kind "static"
    set_languages "c++17"
    -- ...

target "test"
    set_kind "binary"
    set_languages "c++17"
    add_packages "gtest"
    -- ...

target "pyliba"
    add_rules("python.library", {soabi = true})
    add_files("src/*.cpp")
    set_basename("_pyliba")
    add_packages("pybind11")
    set_languages("c++17")
    add_deps("liba")

然后，我想把这个 liba 在另一个xmake项目里使用，大概是下面的样子

-- https://github.com/myrepo/libb.git
package("liba")
    set_description("The liba package")

    add_urls("https://github.com/myrepo/liba.git")
    add_versions("0.0.1", "<shasum256 or gitcommit>")

    on_install(function (package)
        local configs = {}
        if package:config("shared") then
            configs.kind = "shared"
        end
        import("package.tools.xmake").install(package, configs)
    end)

    on_test(function (package)
        -- TODO check includes and interfaces
        -- assert(package:has_cfuncs("foo", {includes = "foo.h"})
    end)
package_end()

add_requires("liba")

target "libb"
    set_kind "shared"
    set_prefixname("")

    set_languages "c++17"
    add_files "source/**.cpp"

    add_packages("liba")

这时候问题出现了，在libb项目里的liba 在 build ok! 之后的 install 环节出了问题，如下：

build cache stats:

cache hit rate: 0%
cache hit: 0
cache miss: 238

[100%]: build ok!

然后我想问的问题是，我能否在 libb 中排除 package liba 中不需要的 targets ？
