X-Git-Tag: v0.1.0~1^2~37

cmake: fix libusb search

Adjust cmake test for libusb library so that the compatible libusb for
freebsd can be found. Since freebsd's libusb header are located in
a different place from libusb-1.0, the includes in the source code must
be adjusted using #include <libusb.h>. Actually those new include
statements are those that libusb-1.0 really expects to be used (see
libusb-1.0.pc cflags to verify this).
