# This CMake script wants to use libusb functionality, therefore it looks
# for libusb include files and libraries.
#
# Operating Systems Supported:
# - Unix (requires pkg-config)
#   Tested with Ubuntu 9.04 and Fedora 11
# - Windows (requires MinGW)
#   Tested with Windows XP/Windows 7
#
# This should work for both 32 bit and 64 bit systems.
#
# Author: F. Kooman <fkooman@tuxed.net>
#

# FreeBSD has built-in libusb since 800069
