xmake require --export 无法导出完整的库文件

描述问题
直接使用 xmake i 命令无法同步打包三方库中的 动态库
尝试使用 xmake require --export <libname> 命令导出时仅导出被导出库的依赖库，但是没有导出库本身。
> xmake require --export --packagedir=./install librdkafka

这里看到动态库编译的 librdkafka 没有被导出, 但是 静态库 编译的依赖 openssl 和 libcurl 的目录被创建了。
期待的结果
- 工程内部脚本域
on_install(function (target))中，如果通过 target 对象获取到自身 deps() 的 package 的 安装路径？ 以允许我通过os.cp()在安装时复制动态库。 - 亦或者，是我使用
xmake require --export存在问题？
工程配置
工程本体(部分)
add_requires("librdkafka", {
system = false,
configs = {
shared = true,
ssl = true -- 连接本地包中的 openssl3
},
debug = false
})
target("capture", function()
add_packages(
"boost",
"librdkafka", -- 其他库不列出
{ public = true }
)
end)
### 附加信息和错误日志
一次xmake f 生成了两个 rdkafka 路径，但是工程内部仅仅 `add_deps` 和 `add_requires` 了一次 librdkafka。

背景信息
工程内部使用 离线的 xmake (xmake g --network=private)，使用 package() 功能描述并安装三方库，package 包的 lua 部分主要参考了 xrepo, 但是包的源码使用 file:// 协议从本地拉取。
其中，cmake 等系统工具使用如下描述：
package("cmake")
set_kind("binary")
add_extsources("dnf::cmake")
其余普通 package 与 xrepo 中区别不大。
最小可复现工程
初始化: xmake create test_kafka
工程 xmake.lua ：
add_rules("mode.debug", "mode.release")
add_requires("librdkafka", {
system = false,
configs = {
shared = true,
ssl = true
},
debug = false
})
target("test_kafka")
set_kind("binary")
add_files("src/*.cpp")
add_packages("librdkafka")

此时使用 xmake require --export --packagedir=./install -vD "librdkafka" 尝试导出 kafka 库文件，
finding librdkafka from xmake ..
checking for xmake::librdkafka ... no
失败，最终没有导出库文件。只导出了前置依赖库 libcurl 和 lz4。
附加信息
注意到 xmake require --info 显示的 librdkafka 的 installdir 在 81642a055b4540d1823df1dec27d8a08， 但是工程内实际搜索和link的目录都是用的 5212c166342b43488a191aba8349bfd6 下的完整库。 这个问题应该是由于 xmake require --export 导致的，重新编译库之后直接查看 info 时只有一个库
发现xmake 查找 xmake::librdkafka 失败了

Title: xmake require --export cannot export the complete library file
Xmake version
3.0.1
Operating system version and architecture
Fedora Linux 42, Linux 6.16.12-200.fc42.x86_64
Describe the problem
Directly using the xmake i command cannot synchronously package the dynamic library in the third-party library
When trying to export using the xmake require --export <libname> command, only the dependent libraries of the exported library will be exported, but the library itself will not be exported.
> xmake require --export --packagedir=./install librdkafka

Here we see that the librdkafka compiled by the dynamic library is not exported, but the directories dependent on openssl and libcurl compiled by the `static library' are created.
Expected results
- In the project internal script domain
on_install(function (target)), if the installation path of the package of its own deps() is obtained through the target object? to allow me to copy the dynamic library on install viaos.cp(). - Or is there a problem with my use of
xmake require --export?
Project configuration
Engineering ontology (part)
add_requires("librdkafka", {
system = false,
configs = {
shared = true,
ssl = true -- connect to openssl3 in local package
},
debug=false
})
target("capture", function()
add_packages(
"boost",
"librdkafka", -- other libraries are not listed
{ public = true }
)
end)
### Additional information and error logs
One xmake f generated two rdkafka paths, but `add_deps` and `add_requires` were used for librdkafka only once inside the project.

Background information
The project uses offline xmake (xmake g --network=private) internally, and uses the package() function to describe and install third-party libraries. The lua part of the package package mainly refers to xrepo, but the source code of the package is pulled from the local using the file:// protocol.
Among them, the use of system tools such as cmake is described as follows:
package("cmake")
set_kind("binary")
add_extsources("dnf::cmake")
The rest of the normal package is not much different from that in xrepo.
