开发板 Qt 应用交叉编译时，find_qt里的qmake处理不当

[ThzShun]

Xmake 版本

3.0.7

操作系统版本和架构

ubuntu 20.04

描述问题

第一个问题是：qt.conf文件和qmake在同一目录的情况下，find_qt.lua，额外引入了bin的一个问题

如图这样修改，就可以正确找到qt.conf文件。至于我这里的qmake和qt.conf是不是规范摆放，就不得而知了，但希望xmake能够提供选项，或者更好的探测。

第二个问题是：当qmake的返回有使用了QT_SYSROOT时，后续的路径如sdkdir、includedir等等，都应该用上这个QT_SYSROOT？

如图这样修改，是可以正确的找到qt相关的头文件，但这里的修改不够完整，后续的编译还会引发错误，所以提了此issue，希望能得到完整的修复。

手动调用qmake的返回如下：

期待的结果

能正常的交叉编译

工程配置

xmake内置的qt widgetapp demo工程。

交叉编译配置如下：

"xmake.additionalConfigArguments": [
        "--sdk=/home/tronlong/RK3506/rk3506_linux6.1_release_v1.1.0/buildroot/output/rockchip_rk3506/host/usr",
        "--qt=/home/tronlong/RK3506/rk3506_linux6.1_release_v1.1.0/buildroot/output/rockchip_rk3506/host/bin"
        "--qt_host=/usr/lib/qt5/bin"
    ],

Title: development board When cross-compiling Qt applications, qmake in find_qt is not handled properly

Xmake version

3.0.7

Operating system version and architecture

ubuntu 20.04

Describe the problem

The first problem is: when the qt.conf file and qmake are in the same directory, find_qt.lua introduces an additional problem with bin

Modify as shown in the figure to find the qt.conf file correctly. As for whether my qmake and qt.conf are placed in a standardized manner, I don't know, but I hope xmake can provide options or better detection.

The second question is: When QT_SYSROOT is used in the return of qmake, should subsequent paths such as sdkdir, includedir, etc. use this QT_SYSROOT?

If you modify it as shown in the figure, you can correctly find the Qt-related header files, but the modification here is not complete enough, and subsequent compilation will cause errors, so I raised this issue and hope to get a complete repair.

The return of manually calling qmake is as follows:

Expected results

Can cross compile normally

Project configuration

xmake's built-in qt widgetapp demo project.

The cross-compilation configuration is as follows:

"xmake.additionalConfigArguments": [
        "--sdk=/home/tronlong/RK3506/rk3506_linux6.1_release_v1.1.0/buildroot/output/rockchip_rk3506/host/usr",
        "--qt=/home/tronlong/RK3506/rk3506_linux6.1_release_v1.1.0/buildroot/output/rockchip_rk3506/host/bin"
        "--qt_host=/usr/lib/qt5/bin"
    ],

Additional information and error logs

No
