The build system has always installed the hidapi.h header to
<hidapi/hidapi.h> relative to the installation prefix.

Wait, the pkgconfig file is doing some weird stuff:

 ❯ cat /usr/lib64/pkgconfig/hidapi-libusb.pc
prefix=/usr
exec_prefix=/usr
libdir=/usr/lib64
includedir=/usr/include

Name: hidapi-libusb
Description: C Library for USB HID device access from Linux, Mac OS X, FreeBSD, and Windows. This is the libusb implementation.
Version: 0.10.1
Libs: -L${libdir} -lhidapi-libusb
Cflags: -I${includedir}/hidapi

includedir=/usr/include

That's fine.

Cflags: -I${includedir}/hidapi

This is unexpected.
