vsxmake 生成工程出现 table index is nil 错误

[VirFunc]

Xmake 版本

2.6.5

操作系统版本和架构

Windows 10 version 21H1

描述问题

在有多层目录的项目中使用 vsxmake 生成 vs 2019 的工程文件会出现 error: table index is nil 错误

期待的结果

能够正常生成 Visual Studio 工程文件

工程配置

目录结构

vsxmake_test
│
├─ src
│  └─ core
│     ├─ lib.cpp
│     └─ xmake.lua
└─ xmake.lua

根目录中的 xmake.lua

set_xmakever("2.6.5")
    set_project("vsxmake_test")
    includes("src/core")

src/core 中的 xmake.lua

target("core")
    set_kind("static")
    add_files("lib.cpp")

src/core/lib.cpp 中包含一个简单的测试函数

#include <stdio.h>

int core_print() {
    printf("test test");
    return 0;
}

如果对工程稍作修改，改成下面这样

将 src/core/xmake.lua 移动到 src/xmake.lua

vsxmake_test
│
├─ src
│  ├─ core
│  │  └─ lib.cpp
│  └─ xmake.lua
└─ xmake.lua

根目录中的 xmake.lua

set_xmakever("2.6.5")
    set_project("vsxmake_test")
    includes("src")

src/core 中的 xmake.lua

target("core")
    set_kind("static")
    add_files("core/lib.cpp")

这样可以正常生成 vs 的工程文件
