Error-prone xmake behaviour when locating system packages

[vspefs]

Xmake Version

2.9.4

Operating System Version and Architecture

Windows 11 21H2 Home. Using msys2, on clang64 environment

Describe Bug

A package holds multiple alias-es, like X, Y and Z. You can find the package using all the alias-es, but the target file to be linked to is named after one of them, for example, Y. When xmake successfully finds the system package and goes on to test if the compiler could actually link against the library, it tests only by adding the compiler flag "-lX", in which X is the package name we specify in our xmake.lua, instead of the real name we should use, Y.

Expected Behavior

Whichever package name we specify in xmake.lua, xmake could use the right name for the target file while testing if the library links.

Project Configuration

-- xmake.lua
-- add_requires("glfw") -- this makes xmake fail to locate the system package, as glfw's target file is named "libglfw3.a/.so"
add_requires("glfw3")

set_languages("c++latest")
add_rules("mode.debug", "mode.release")

target("main")

    set_kind("binary")

    add_files("main.cpp")

    -- add_requires("glfw")
    add_packages("glfw3")

// main.cpp
#include <print>
#include <GLFW/glfw3.h>

int main(void)
{
    // c++ test
    std::println("Hello, world!");

    // glfw test
    glfwInit();
    glfwTerminate();
}

note: install or modify (m) these packages (pass -y to skip confirm)?
in xmake-repo-from-github:
  -> glfw 3.4 [toolchains:"clang"]
please input: y (y/n/m)

As you see, it fails to locate the system package.

[waruqi]

you can open a pr to add add_extsources or on_fetch to improve to find system library for glfw package.

e.g. add_extsources("pkgconfig::glfw3")

https://github.com/xmake-io/xmake-repo/blob/8822e12a8bd9a85bb34b13bacbe1a0899968c964/packages/g/glfw/xmake.lua#L23

and you can refer other packages in xmake-repo

It work for me= =
