为什 么rootfs不包含libmodbus呢？如何解决？

我已经使用 Distribution-Package 成功构建了 st-image-weston。
现在我想将 libmodbus 添加到 st-image-weston。
1)
我检查了下面路径中的 libmodbus 配方。
我正在使用包含 libmodbus 的 meta-oe 层。
但是我在目标中找不到 libmodbus。
为什么 rootfs 不包含 libmodbus？

• layers/meta-openembedded/meta-oe/recipes-extended/libmodbus
  

2)
我尝试通过执行以下命令来添加 libmodbus。
发生以下错误。
如何解决？

• echo 'IMAGE_INSTALL_append += "libmodbus"' >> ../layers/meta-st/meta-st-openstlinux/recipes-st/images/st-image-weston.bbappend
  

• bitbake st-image-weston -c cleanall
• bitbake st-image-weston
