buildroot增加sysytemd出错

[migu_]

各位大佬，我在尝试为buildroot中增加systemd时出现错误。在编译到libusb时，出现以下问题
2022-11-14T14:43:19 checking for library containing clock_gettime... none required
2022-11-14T14:43:19 checking libudev.h usability... no
2022-11-14T14:43:19 checking libudev.h presence... no
2022-11-14T14:43:19 checking for libudev.h... no
2022-11-14T14:43:19 configure: error: "udev support requested but libudev not installed"
然后我检查了配置，找到libgudev，发现已经选中。不知道各位有什么思路吗。
