[yocto] can't find libudev.h

[Derek Dresser]

Hello,  I am trying to build a recipe that has a header dependency on
libudev.h.  I have added a

DEPENDS += "systemd"

because it looks like systemd provides libudev, but I continue to get the
following error:

   hid.c:44:21: fatal error: libudev.h: No such file or directory

This is what a find shows:

find /build -name libudev.h 2>/dev/null
/build/multiplexor-glibc/work/corei7-64-oe-linux/systemd/1_241-r0/git/src/libudev/libudev.h
/build/multiplexor-glibc/work/corei7-64-oe-linux/systemd/1_241-r0/sysroot-destdir/usr/include/libudev.h
/build/multiplexor-glibc/work/corei7-64-oe-linux/abc-app/0.1-r0/recipe-sysroot/usr/include/libudev.h
/build/multiplexor-glibc/work/intel_corei7_64-oe-linux/image-multiplexor-dev/1.0-r0/rootfs/usr/include/libudev.h
/build/multiplexor-glibc/sysroots-components/corei7-64/systemd/usr/include/libudev.h

Any thoughts on how to resolve or troubleshoot this are appreciated.
