./hidapi/hidapi/hidapi.h: No such file or directory

Question

I cloned go-ethereum, and used go mod vender. When make, it's failed! and the error info is:

# github.com/karalabe/usb
vendor/github.com/karalabe/usb/hid_enabled.go:22:10: fatal error: ./hidapi/hidapi/hidapi.h: No such file or directory
   22 | #include "./hidapi/hidapi/hidapi.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Ran into the same issue when deploying to Google App Engine the other day.

A workaround is to

$ go mod vendor
$ cd vendor/github.com/karalabe
$ rm -rf usb
$ git clone https://github.com/karalabe/usb

This solves the problem of missing files I have no idea though if there are other unwanted side effects! So use with caution.
