Cannot find libudev.h

Hello, I want to create application with need to automaticly detecting usb storage devices. For that task I want to use API from libudev.h and on the board I have libudev.so, but I can’t find header file libudev.h.
I built OS for device based on Colibri-iMX6ULL_Console-Image.bootfs downloaded form Toradex.
Where I can find libudev.h which will work with libudev.so that I have on the board. (libudev.so present on default rootfs Colibri-iMX6ULL_Console-Image.bootfs Toradex )

linbudev.h included in SDK (https://developer.toradex.com/getting-started/module-2-my-first-hello-world-in-c/configure-toolchain-colibri-imx6-ull?som=colibri-imx6ull&board=iris-carrier-board) to do a cross compiling.

Though native compilation is possible we do not support it.
