这个怎么测

How to test this

[star-hengxing]

可以在 xmake/modules/private/action/require/impl/actions/test.lua 添加 _test_pkgconfig 函数

• 检测 includedirs/links 是否和 package 匹配，预防一些 corner case（libxml2/x264）。
• 检测 package:name 和 pc file name 是否一样，如果不一样可以在 verbose 下打印提醒。

You can add the _test_pkgconfig function in xmake/modules/private/action/require/impl/actions/test.lua

• Check whether includedirs/links matches package to prevent some corner cases (libxml2/x264).
• Check whether package:name and pc file name are the same. If they are different, you can print a reminder under verbose.

这种感觉只能加 warning 要是直接 abort 估计得 break 一堆包，而且很多包 有很多的子库，和多个 pc 的，全是跟包名不同的 怎么搞，比如 abseil

This feeling can only be added with warning. If you directly abort, you will probably have to break a bunch of packages.

install 后，可以用 ldd 对动态库检查一下是否用了系统包管理的库，这样就可以知道有没有依赖没拆

After install, you can use ldd to check whether the dynamic library uses the system package management library, so that you can know whether there are any dependencies that have not been removed.

很多都是不同的，内置检测不太好搞，会有很多 warning 误报，像 libxml2 就是 lib/pkgconfig/libxml-2.0.pc 不是 libxml2.pc

这种要么搞成 package:check_pkgconfig("libxml-2.0.pc") 在 on_test 根据不同包的情况 按需测。

Many are different. The built-in detection is not easy to do. There will be many warning false positives. For example, libxml2 is lib/pkgconfig/libxml-2.0.pc, not libxml2.pc

This can be done as package:check_pkgconfig("libxml-2.0.pc") in on_test and tested on demand according to the situation of different packages.

试下这个 patch #6055
We can check pkgconfig/cmake importfiles

package("libxml2")
    on_test(function (package)
        assert(package:check_importfiles("pkgconfig::libxml-2.0"))
    end)

package("x264")
    on_test(function (package)
        assert(package:check_importfiles()) -- default: pkgconfig::x264
    end)

package("libcurl")
    on_test(function (package)
        assert(package:check_importfiles("cmake::CURL"))
    end)

> checking for pkgconfig/x264
checking for pkg-config ... /usr/local/bin/pkg-config
{
  includedirs = {
    "/Users/ruki/.xmake/packages/x/x264/v2024.02.27/7d8fe89a9dc648139ce022fac2728184/include"
  },
  version = "0.164.3192",
  links = {
    "x264",
    "pthread",
    "m",
    "dl"
  },
  linkdirs = {
    "/Users/ruki/.xmake/packages/x/x264/v2024.02.27/7d8fe89a9dc648139ce022fac2728184/lib"
  }
}

改了下，用 package:check_importfiles 更合理些，并且具有扩展性，还可以检测 cmake 的导入文件

After changing it, using package:check_importfiles is more reasonable and extensible. It can also detect the import files of cmake.
