Subject: [PATCH] cmake: Fix header detection with CheckUSBHID

Make use of check_include_files to be able to also include
stdint.h when checking for the headers. Fixes detection of
usbhid.h on OpenBSD.

/usr/include/usbhid.h:40:2: error: unknown type name 'uint32_t'
   40 |         uint32_t _usage_page;
      |         ^

(cherry picked from commit 410a35fbee9c2211f6d824c2d65b44d22009212d)
(cherry picked from commit 0c7042477ae010b8c6b1704e4befe3bd5dfcbe57)
